Oh, hmm, that's something we already have to do elsewhere to get
standard conforming interfaces on that platform:
# Some platforms use these, so just define them. They can't hurt if they
# are not supported. For example, on Solaris -D_POSIX_PTHREAD_SEMANTICS
# enables 5-arg getpwuid_r, among other things.
PTHREAD_CFLAGS="$PTHREAD_CFLAGS -D_REENTRANT -D_THREAD_SAFE
-D_POSIX_PTHREAD_SEMANTICS"
