I was almost sure that it should work as you say and
I tried and it seemed
to work fine. Just wanted to double check. Major fear
was about each cmpiler
version needing his own (different) libs.

I've just posted the new distrib (20090615) with:

        - gcc3 wmt/gmt
exes
        - gcc4 wmt/gmt
exes

MaX.
