   gcc3 does support this on Mac OS X /  Darwin.  A couple things to try:

- configure with CC="cc -no-cpp-precomp' to disable the old style 
precompiled header support (2.95.x does not understand vararg macros).
- Select gcc3 as your default compiler with:
        sudo gcc_select 3

   I don't recall whether gcc3 defaults to using old precomps -- I think 
not, but neither of these alone fixes the problem, both together 
should.  I use vararg macros on Mac OS X all the time, so it is 
definitely supported :)
