Perhaps I'm being dense, but I still don't get a warning.  This of
course, does not negate the fact that we need hex constants.

I'm attaching a build of cc1 for the curious.  No warning.  This is my
stage1 compiler:

       gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)

perhaps it's in stage2 or something.
