Subject: 1998-09-12  Ben Elliston  <bje@cygnus.com>

        * {most}.c: Include <errno.h> to get POSIX error values.

        * signal.c (pthread_sigmask): Only provide if HAVE_SIGSET_T is
        defined.

        * config.h: #undef features, don't #define them.  This will be
        generated by autoconf very soon.
