    Add a #ifdef HAVE_UNISTD_H check to buffers.c
    
    Reported on tor-dev by Gisle Vanem.  Bug not in any released Tor
    
    (The suggested patch used _MSC_VER, but that's not how we do stuff
    with autoconf.  With autoconf, you detect the feature you want,
    rather than trying to list all the systems that do or do not have
    it.)
