Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:

    Here is another fix, which addresses a few more or less severe bugs in
    configuration and unix/posix:

    * Configuration fix: c/src/lib/configure.in didn't handle RDBG correctly

    * Configuration fix: make depend was non-functional in
      c/src/lib/libc/Makefile.in
    * Configuration fix: stray comment removed from aclocal/target.m4

    * RTEMS fix: termios support for unix/posix now uses the host's headers
      only (was completely broken).
    - Don't install RTEMS's newlib sys/termios.h for unix (sys/termios.h
      apparently is a newlib specific header)
    - To be able to compile RTEMS's  termios.c with glibc2.1, glibc-2.1
      needs __USE_MISC, which is a private define from gcc's features.h, being
      defined only when _BSD_SOURCE of _SVID_SOURCE is defined.  RTEMS's
      termios apparently implements BSD, thus -D_BSD_SOURCE was added to
      Linux-posix.cfg.
    - Conflicting definitions for  __USE_MISC and _BSD_SOURCE inside of
      RTEMS codes removed due to definition of _BSD_SOURCE on the toplevel.

    This fix has been tested with linux/posix (primary glibc2.1 native),
    linux/posix (secondary libc5 native), sh/gensh1, i386/pc386 and a couple
    of other bsp's/CPU.

    To apply:

        cd <srcdir>
        patch -p1 < rtems-rc-19990709-9.diff

    and
        aclocal -I aclocal && automake && autoconf
        cd c/src/lib; autoconf

    or
        ./autogen
