I don't think this is a good idea.
By keeping the emphasis on GCC2 for Haiku R1 we can do a clean break
with R2 - that means full backwards compatibility, and still have all
the great API changes for GCC 4 compiled apps.
If we switched to GCC4 now, we would just break compatibility for no
better reason than the choice of the default compiler. Projects that
really need it can use it, but they know that their software will no
longer run without a recompilation on future Haiku releases.
IOW as long as no one forces you to use GCC4, you should use GCC2 for
now.
Of course, this is pretty much independent from having Haiku compiled
with GCC4, but since it's much better tested with GCC2, and our GCC4
version is not really up-to-date, but has some known problems, as well
as some pending bugs (like the Radeon driver Rene mentioned), I don't
see good reason to do so shortly before a release.
Bye,
Axel.
