Right now the officially recommended version of PowerPC gcc is still
2.95.2, as per the installation instructions on
sources.redhat.com/ecos. However for the upcoming 2.0beta release we
have been testing with gcc 3.2.1/binutils 2.13.1/gdb 5.3, and for
PowerPC that seems to work fine without patches. Earlier 3.x.y
versions of gcc cannot be used for eCos because of a generic gcc bug.
I have not tried 3.2.2 for PowerPC yet. There is definitely a problem
with 3.2.2 and the i386-elf target, but that particular problem won't
affect powerpc-eabi.
