coreutils-4.5.9: Compaq/DEC OSF/1 4.0, a success, and a patch for a failure

The coreutils-4.5.9 on Compaq/DEC OSF/1 4.0 with gcc-2.95.3 succeeded,
and all tests passed.

However, a build with c89 failed like this:

        c89 -DLIBDIR=\"/usr/local/lib\" -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I.  
-I/usr/local/include  -g -c `test -f 'mmap-stack.c' || echo
        './'`mmap-stack.c
        cc: Error: mmap-stack.c, line 71: In this statement, "stack" and "(-1)" 
cannot be compared for equality or inequality. (noequality)
          if (stack == MAP_FAILED)
        ------^
        make[3]: *** [mmap-stack.o] Error 1

I applied this simple patch:

        diff lib/mmap-stack.c.~1~ lib/mmap-stack.c
        71c71
        <   if (stack == MAP_FAILED)
        ---
        >   if (stack == (void*)MAP_FAILED)

and restarted the build.  It then completed successfully, and all
tests passed.
