 I just wanna make sure it is not broken just for me (which is possible if
 I do something wrong).

 You do mean the current mainstream version then? I can try, but not
 promise when.
 Why don't you ask on one of the mailing lists, or file a ticket? After all
 my system isn't really relevant for what you're doing.

 Not exactly. GCC is very good at backward compatibility with older OS
 versions, but not so much with older build systems. You could try to
 figure out where the earlier `_DARWIN_C_SOURCE` definition comes from, but
 redefining a token is in no way an error in C (AFAIK!) so at least the
 `-Werror` argument would have to be dropped from CFLAGS during these
 tests.
