Comment (by kencu):

I'll put up the patched version of `compiler-
rt/lib/builtins/os_version_check.c` with a small test program attached to
it to drive it.

It works for me on 10.4 and up, building it with:
{{{
clang -Wall -framework CoreFoundatation -o test_osversion
ken_os_version_check_clang-6.c
}}}
or
{{{
gcc -Wall -framework CoreFoundatation -o test_osversion
ken_os_version_check_clang-6.c
}}}
Interestingly, if you don't link in CoreFoundation the code does not
error, but does not actually run the test or do anything either. Should
probably return "-1" or something in that case, but have to ask the
compiler_rt guys about that I guess :>
