What about gcc-2.95 ?

I think I would have preferred a more consistent numbering system - a bit 
like BOOST_VERSION maybe:

#define BOOST_GCC (__GNUC__*10000 + __GNUC_MINOR__ * 100 + 
__GNUC_PATCHLEVEL__)

Of course even that can in theory go wrong, but it does make checks easier 
to read (because of greater consistency between gcc 2 and 3):

#if BOOST_WORKAROUND(BOOST_GCC, <= 29500)
#else BOOST_WORKAROUND(BOOST_GCC <= 30400)
// etc....

Any other thoughts?

John.
