        * rdi-share/hsys.c: to compile under 4.4BSD derived systems (FreeBSD,
        NetBSD...) sys_errlist should not be declared in hsys.c.
        NEED_SYSERRLIST is set already by configure, so we can use it.
        * rdi-share/unixcomm.c: 4.4BSD derived systems define BSD, but are
        posix compliant and we should not work with the old compatibility
        stuff.  Because of that I undef BSD in case of FBSD etc and include
        sys/ioctl to get the flags.
        * rdi-share/unixcomm.c: If the TIOCEXCL flags exists set serial line
        for exclusive use.
