I built a x86 -> powerpc cross-compiler, then used that to build a native powerpc compiler but on the x86 machine. Finally used the resulting compiler on a real powerpc box to create the proper compiler! I had begun the same process to port other compilers too (some failed, some succeeded, cross-compiling is a very tricky job), but I was too busy to keep it up. Anyway, I stopped when trying to build alpha gnat packages, cross-compiling simple programs might work but for compilers the 32-bit <-> 64-bit cpu difference screws things up.
