Isn't fnmatch.h shared with gnulib? I don't feel like I understand
the constraints on code shared with gnulib, certainly not enough to
call it "obvious." Also, some of the conditionals in there don't make
sense to me ("#if !defined _POSIX_C_SOURCE || _POSIX_C_SOURCE < 2 ||
defined _GNU_SOURCE" -- what's that even supposed to do?)

* libio/libio.h: Use __USE_GNU, not _GNU_SOURCE, in a conditional.
* test-skeleton.c: Include stdint.h to ensure uintptr_t is available.
