Hi!
Older glibcs used to declare fwrite with -D_FORTIFY_SOURCE{,=2} as
warn_unused_result.
The following is just an workaround against that, not really using it in the
end, but just letting the compiler think we are.
Bootstrapped/regtested on x86_64-linux and i686-linux, committed to trunk.

* libgomp.h (gomp_print_string): Change return type from void to int.
* affinity-fmt.c (gomp_print_string): Likewise. Return true if
not all characters have been written.
