I always learn a lot when I read your posts :o)  From playing around
with the ideas you suggested I notice that the behavior of -dumspecs
seems to be different for the two compilers:  the predefines are
printed out for gcc2 but not for gcc34, apparently.  Any idea why?

Also, as I said in my previous post, the gcc34 from the ports seems
to work much better at compiling ports than my patched system gcc34,
and it predefines only __FreeBSD_=4.

I'm away for the next week, but I'll play with this more when I get
back.

As always, thanks for your excellent help.
