        vfork() works like fork() 'cept that the parent gets
        suspended until the children call exit(), IIRC.

        You shouldn't do that.  Try adding this to your configure
        arguments:

                --includedir=/usr/ucbinclude

        which will pass -I/usr/ucbinclude to all the Makefiles.

        Though, why it requires you to use something out of ucb,
        I'll never know.

        They've changed the build process on gcc a lot over the past
        five years, though.

        vfork.h doesn't have much to do with threads, so this won't
        change anything.

        I would download a pre-compiled gcc and then use that
        gcc to compile, actually.  If it works, great!  If not,
        you've still got the original.

        Are you following the instructions in INSTALL or are you
        doing a ./configure; make; make install?  I don't know
        if the configure/make/make install route correctly builds
        the three compilers or not.  I'm a weenie and always do
        the hard way (make bootstrap; make stage1;  etc.)
