> I built the latest gcc 4.3.0 and binutils 2.18+ snapshots yesterday and
successfully built rockbox for the iriver h300 with that, some small changes
to rockbox code were necessary though. If you just want to build rockbox I
recommend the recommeded combination of gcc 3.4.6 (possibly with lear's
patch) and binutils 2.16.1, but if you want to experiment with compilers I
think gcc 4.3 is more fun :-) If you are interested in my patches I will
post them somewhere for you.
