I ran into this a couple of days back. I pulled tag apple-gcc-4020 off
the cvs and built it.
Because I wanted fortran, libffi and libobjc-gnu I futzed about with
the build_gcc script that sets the options on the build. Unwittingly,
I changed a version number in the script and it tried to build a 64bit
libgcc with -m64 option. It fell over at the first hurdle because I
did not have the ppc64 headers, which I presume are unavailable outside
Apple.
I will post the good news in a separate message.
