I find that gcc 2.3.1 doesn't handle -DFOO -UFOO as it used to.
The -U option seems to be ignored in this case, whereas up to gcc 2.2.2
it would override the -D option.  This is the behavior that is 
documented and that other C compilers seem to prefer as well.
gcc -Upredefined_symbol seems to have stopped working as well.

Incidentally, this breaks the compile of the MIT R5 XsunMono server.

here is a clue from ChangeLog:

Fri Oct  2 20:03:53 1992  Richard Stallman  (rms@mole.gnu.ai.mit.edu)

        * cccp.c (main): Handle -U before -D (and -A).

What's the story?
