gcc.c-torture/execute/builtins/fputs.c: fputs_unlocked prototype
Current glibc headers only declare fputs_unlocked for _GNU_SOURCE,
so define it to obtain an official prototype.
Add a fallback prototype declaration for other systems that do not
have fputs_unlocked. This seems to the most straightforward approach
to avoid an implicit function declaration, without reducing test
coverage and introducing ongoing maintenance requirements (e.g.,
FreeBSD added fputs_unlocked support fairly recently).
gcc/testsuite/
* gcc.c-torture/execute/builtins/fputs.c (_GNU_SOURCE):
Define.
(fputs_unlocked): Declare.
