# So far with the Darwin gnat-bootstrap binary packages, there have been two
# types of dylib path references to other dylibs that need fixups:
#
# 1. Dylibs in $out/lib with paths starting with
# /Users/runner/.../gcc/install that refer to other dylibs in $out/lib
# 2. Dylibs in $out/lib/gcc/*/*/adalib with paths starting with
# @rpath that refer to other dylibs in $out/lib/gcc/*/*/adalib
#
# Additionally, per Section 14.4 Fixed Headers in the GCC 12.2.0 manual [2],
# we have to update the fixed header files in current Alire GCC package, since it
# was built against macOS 10.15 (Darwin 19.6.0), but Nix currently
# builds against macOS 10.12, and the two header file structures differ.
# For example, the current Alire GCC package has a fixed <stdio.h>
# from macOS 10.15 that contains a #include <_stdio.h>, but neither the Alire
# GCC package nor macOS 10.12 have such a header (<xlocale/_stdio.h> and
# <secure/_stdio.h> in 10.12 are not equivalent; indeed, 10.15 <_stdio.h>
# says it contains code shared by <stdio.h> and <xlocale/_stdio.h>).
