If anyone feels up to it that can try to help with the FSF gcc development.
You can commit patches of up to 20 lines without paperwork which often is
plenty to fix bugs with. I just fixed the P1 block on *-*-darwin* last night...


The biggest issue left to be addressed is how FSF gcc and darwin handle
libgcc. Apple wanted to standardize it so we ended up with libgcc-10.4
and libgcc-10.5 which define which symbols out of libgcc_s are visibie.
This is causing us problems since over time new symbols have been added
to libgcc_s and they aren't visible. We are working with the Darwin 
maintainers from Apple to try to find the best solution around that.
If we fix that, I actually think we are in pretty good shape for awhile.
Our testsuite results compare very well with any other FSF gcc target.
