It is not OK in FreeBSD, either. This is what I noted in the Gnulib manual: https://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=doc/posix-functions/random.texi But it is MT-safe in NetBSD (in the '#ifndef SMALL_RANDOM' branch): http://cvsweb.netbsd.org/bsdweb.cgi/src/common/lib/libc/stdlib/random.c?rev=1.7&content-type=text/x-cvsweb-markup Bruno -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
