// Test that a [no_undeclared_headers] module can include builtin headers, even

// if these have been "claimed" by a different module that wraps these builtin
|

// headers. libc++ does this, for example.

// The test inputs used here replicates the relationship between libc++ and
|
||
|
|
// glibc. When modularizing glibc, [no_undeclared_headers] must be used to

|

// prevent glibc from including the libc++ versions of the C standard library
|

// headers.
