+#===============================================================
+# Filename : macsimum
+# Purpose  : Builds Mac-to-Linux cross-compiler toolchains.
+# Authors  : Zach van Rijn <me@zv.io>
+# License  : MIT
+# Revision : 20200303
+#===============================================================
+
+#---------------------------------------------------------------
+# README
+#
+# overview
+# --------
+#
+# This script builds "musl-cross-make" cross-compiler toolchains
+# that are hosted on macOS and target Linux. For example, your
+# Macintosh machine can use up-to-date versions of GCC to build
+# code (C, C++, Fortran) for your MIPS router. The libc used is
+# called 'musl': https://www.musl-libc.org/faq.html
+#
+# Others have tried and failed to deliver what you're able to do
+# with this tiny script.
+#
+# What does this look like? Modern GCC that does:
+#
+#   * macOS --> ARM, Motorola 68000, MIPS, OpenRISC, PowerPC,
+#               RISC-V, S/390, SuperH, x86-based, more?
+#
+# The goal, of course, is to achieve parity with musl.cc's Linux
+# offerings. A link to pre-built macOS binaries is now public,
+# and this is the script to reproduce them. https://mac.musl.cc/
+#
+#
+# requirements
+# ------------
+#
+# Basically, you need XCode Command Line Tools. I don't know any
+# specific version requirements, but if you encounter problems I
+# would appreciate a heads up.
+#
+# This document may be useful: https://git.zv.io/snippets/34/raw
+#
+# You'll also need a working internet connection.
+#
+# A previous version of this script relied on Homebrew for some
+# of the utilities that we're using. This, contrary to intent,
+# created a Homebrew dependency. No longer! Build products are
+# now fully portable (across compatible macOS / OS X versions).

+# Build configuration
+
+##
+# It is possible to build all library and utility dependencies
+# for the building of musl-cross-make production toolchains on a
+# RAM disk. This may improve performance on systems with slow
+# disks, and requires approximately 3GB of space. 4GB is safe:
+#
+#   $ diskutil erasevolume HFS+ "RAMDISK"                      \
+#     `hdiutil attach -nomount ram://$((2048 * 1024 * 4))`
+#
+# The '4' in the above example represents gigabytes.
+
+rdsk=/Volumes/RAMDISK;          # dependency build prefix
+
+##
+# When the production toolchains are built, a significant bit of
+# disk space is required. Do not attempt to build them in RAM if
+# you are not on a server server with several dozen gigabytes of
+# RAM and the assurance that your system won't crash :)
+
+bdsk=/tmp;                      # production build prefix
+
+##
+# This directory will contain dependency build trees. It can be
+# deleted after the toolchains are built.
+
+bdir=${rdsk}/tmp;               # scratch directory location
+
+##
+# Within each dependency build tree, we want to perform an out-
+# of-tree build. This is the (arbitrary) name of that directory.
+
+tdir=x;                         # out-of-tree directory name
+
+##
+# This directory will contain the dependency libraries and tools
+# and can also be deleted after the toolchains are built, but it
+# may be useful to maintain this directory for future builds.

+#===============================================================
+# Filename : scripts/sinner
+# Purpose  : Builds Linux-to-Windows cross-compiler toolchains.

+#===============================================================

+#---------------------------------------------------------------
+# README
+#
+# overview
+# --------
+#
+# This script builds "musl-cross-make" cross-compiler toolchains
+# that are hosted on Linux and target Windows. For example, your
+# MIPS router can use up-to-date versions of GCC to build code
+# (C, C++, Fortran) for your Windows XP machine. The libc used
+# is called 'musl': https://www.musl-libc.org/faq.html
+#
+# Others have tried and failed to deliver what you're able to do
+# with this tiny script. Additions to this list are welcome:
+#
+# What does this look like? Modern GCC that does:
+#
+#   * Linux on ARM, Motorola 68000, MIPS, OpenRISC, PowerPC,
+#              RISC-V, S/390, SuperH, x86-based, more?
+#
+#         --> Windows XP to 10, and possibly older.
+#
+# The goal, of course, is to achieve parity with musl.cc's Linux
+# offerings. This is the script to build the binaries located at
+# https://more.musl.cc/YOUR-HOST-ARCHITECTURE/*-w64-mingw32.zip
+#
+#
+# build platforms
+# ---------------
+#
+# You need Linux to build these, and an architecture that runs a
+# toolchain from musl.cc.
+#
+#
+# requirements
+# ------------
+#
+# Consider running this script inside of an isolated environment
+# such as a container or virtual machine. While not required, we
+# do not recommend running any foreign scripts or binaries in an
+# important environment. You'll need the following packages:
+#
+#   * cmake
+#   * curl
+#   * git
+#   * make
+#   * patch (GNU)
+#   * tar
+#   * xz
+#   * zip
+#
+# e.g., apk add cmake curl git make patch rsync tar xz zip
+#
+#
+# other notes
+# -----------
+#
+#   * A prior version of this script ('prepare') relies on Linux
+#     'binfmt_misc' and QEMU to emulate certain build byproducts
+#     and requires root privileges to install (but not use) that
+#     setup. This version cross-compiles the toolchains purely.
+#
+#   * This script uses the 'mingw-cross-make' flavor maintained
+#     at https://git.zv.io/toolchains/mingw-cross-make to build
+#     MinGW toolchains. Issues should be addressed there.
+#
+#
+# usage
+# -----
+#
+#   $ ./scripts/sinner [TRIPLE ...]
+#
+#   $ ./scripts/sinner i686-w64-mingw32 x86_64-w64-mingw32
+
+#---------------------------------------------------------------
+# Configuration.
+
+## Component Versions
+#
+# These options are self explanatory, but *must* correspond to a
+# supported version within the "musl-cross-make" repository. One
+# other factor to consider is that kernel headers and musl libc
+# will be harvested from a "donor" toolchain; these versions do
+# not necessarily correspond to what is built here (yet, TODO).
+#
+GCC_VER=9.1.0
+BINUTILS_VER=2.32
+MUSL_VER=git-a60b9e06861e56c0810bae0249b421e1758d281a
+GMP_VER=6.1.2
+MPC_VER=1.1.0
+MPFR_VER=4.0.2
+MINGW_VER=git-3e6c10aeba81c589a7b2ed1e7daee4d4d75b646e
+
+## Directories
+#
+# By default, all toolchains that can be built, are built. This
+# requires a significant amount of disk space. Please ensure you
+# have at least 50GB of free disk space in these directories:
+#
+base="${HOME}/sinner_src"       # base source directory
+huge="${HOME}/sinner_bld"       # base  build directory
+logs="${HOME}/sinner_log"       # suite build log directory
+zips="${HOME}/sinner_bin"       # completed toolchains go here
+
+## Toolchain Mirror
+#
+# If you have access to an x86_64 Linux machine, or one that has
+# an x86_64 QEMU user-mode emulator registered in 'binfmt_misc',
+# you will always be using the latest available software.
+#
+musl=https://more.musl.cc       # more.musl.cc or mirror
+
+## Toolchain Naming Conventions
+#
+# The musl.cc toolchains follow a simple naming convention: all
+# cross compilers are suffixed with '-cross', native '-native'.
+# If you're using a different mirror or convention, set it here.
+#
+csuf=-cross                     # cross  suffix
+nsuf=-native                    # native suffix
+
+## Toolchain Tuples
+#
+# Values can be found at 'https://more.musl.cc/' where the $user
+# variable corresponds to your build platform, and $host to your
+# intended Linux development environment. Note that unless the
+# website says otherwise, only the 'x86_64-linux-musl' toolchain
+# directory is up-to-date. If you can't find what you're looking
+# for you must build a MinGW-w64 suitable toolchain from source.
+#
+user=x86_64-linux-musl          # platform that builds suite
+
+## Build Environment
+#
+# This variable is extended during the toolchain download step.
+#
+kale="${base}/${user}${csuf}/bin";
+
+## Repositories
+#
+# The build infrastructure used is called "musl-cross-make" and
+# is upstream https://github.com/richfelker/musl-cross-make, but
+# this version is incompatible with the current script. It's out
+# of date, too, so please leave the default unless you fork it.

+
+## Suite Targets
+#
+# Now that RISC-V patches are (unofficially) merged into musl, a
+# single text file with target tuples (which comprise the suite)
+# may now be used. Modify this with e.g. a pastebin link if you
+# wish to use a different list (this one is self-updating).

+#
+# In absolute theory, one can build this toolchain suite using a
+# "native" toolchain from 'musl.cc' suitable for your platform,
+# to build a MinGW-w64 cross-compiler (hosted on your platform,
+# targeting i686- or x86_64- Windows), then use that toolchain
+# to build the suite. Some may exist here: https://more.musl.cc/
+#
+# In practice, you just need 'i686-w64-mingw32-cross' for 32-bit
+# or 'x86_64-w64-mingw32-cross' for 64-bit that runs on your own
+# Linux (or Windows, with Cygwin or MSYS2) system.
+#
+#
+# requirements
+# ------------
+#
+# Consider running this script inside of an isolated environment
+# such as a container or virtual machine. While not required, we
+# do not recommend running any foreign scripts or binaries in an
+# important environment. You'll need the following packages:
+#
+#   * cmake
+#   * curl
+#   * git
+#   * make
+#   * patch (GNU)
+#   * rsync
+#   * tar
+#   * xz
+#   * zip
+#
+# e.g., apk add cmake curl git make patch rsync tar xz zip
+#
+# You'll also need an internet connection (or manually do so) to
+# obtain corresponding "donor" toolchains from musl.cc; what we
+# are doing is pulling musl and the Linux kernel headers from an
+# existing toolchain, rather than fuss with getting them to play
+# nicely with the "Canadian" cross infrastructure.
+#
+#
+# other notes
+# -----------
+#
+#   * Toolchains cannot be built with kernel headers; these are
+#     copied into the output directory after the initial build.
+#     Kernel version is that of donor toolchain.
+#
+#   * Toolchains cannot be built with the musl library; this is
+#     copied into the output directory after the initial build.
+#     musl version is that of donor toolchain, but may be flaky.
+#
+#   * If you do not uncomment the 'nano' line, you will build a
+#     large number of toolchains. This requires an exceptional
+#     amount of disk space and time. This is what I use it for.
+#
+#
+# to-do
+# -----
+#
+#   * Fix underlying issue causing kernel headers and musl to be
+#     not built or installed correctly.
+#
+#   * Generate Cygwin (and/or MSYS2) packages for distribution.

+# Configuration.
+
+## Component Versions
+#
+# These options are self explanatory, but *must* correspond to a
+# supported version within the "musl-cross-make" repository. One
+# other factor to consider is that kernel headers and musl libc
+# will be harvested from a "donor" toolchain; these versions do
+# not necessarily correspond to what is built here (yet, TODO).
+#
+GCC_VER=9.3.0
+BINUTILS_VER=2.34
+MUSL_VER=git-0a005f499cf39822166dd4db3d2d31f0639f1b1b
+GMP_VER=6.2.0
+MPC_VER=1.1.0
+MPFR_VER=4.1.0
+LINUX_VER=5.4.50               # TODO: proper install, no rsync
+
+## Directories
+#
+# By default, all toolchains that can be built, are built. This
+# requires a significant amount of disk space. Please ensure you
+# have at least 50GB of free disk space in these directories:
+#
+base="/tmp/winner_src"       # base source directory
+huge="/tmp/winner_bld"       # base  build directory
+logs="/tmp/winner_log"       # suite build log directory
+zips="/tmp/winner_bin"       # completed toolchains go here
+
+## Toolchain Mirror
+#
+# If you have access to an x86_64 Linux machine, or one that has
+# an x86_64 QEMU user-mode emulator registered in 'binfmt_misc',
+# you will always be using the latest available software.
+#
+musl=https://more.musl.cc       # more.musl.cc or mirror
+
+## Toolchain Naming Conventions
+#
+# The musl.cc toolchains follow a simple naming convention: all
+# cross compilers are suffixed with '-cross', native '-native'.
+# If you're using a different mirror or convention, set it here.
+#
+csuf=-cross                     # cross  suffix
+nsuf=-native                    # native suffix
+
+## Toolchain Tuples
+#
+# Values can be found at 'https://more.musl.cc/' where the $user
+# variable corresponds to your build platform, and $host to your
+# intended Windows development environment. Note that unless the
+# website says otherwise, only the 'i686-linux-musl' toolchain
+# directory is up-to-date. If you can't find what you're looking
+# for you must build a MinGW-w64 suitable toolchain from source.
+#
+user=i686-linux-musl            # platform that builds suite
+host=i686-w64-mingw32           # platform that   runs suite

+## Repositories
+#
+# The build infrastructure used is called "musl-cross-make" and
+# is upstream https://github.com/richfelker/musl-cross-make, but
+# this version is incompatible with the current script. It's out
+# of date, too, so please leave the default unless you fork it.

+## Suite Targets
+#
+# Now that RISC-V patches are (unofficially) merged into musl, a
