Some time ago, someone asked this list about gm2 on PPC Mac. The
following query and response should help. Basically, first build GCC-10
and then use it to build GCC-13.
I have not tried it yet because my G5 is currently unavailable but I
shall try it.

Subject: last version of gcc for 32 bit power pc mac?
I have a ~20 year old 32 bit Power PC macintosh system that still runs.
Yup .. me too - my oldest oldest is a 500MHz power mac AGP (runs darwin8
and takes 3 days to bootstrap the compiler and a week to test it)..
.. but mostly I work on a Quad G5.
Can someone tell me the most recent version of GCC that still supports
GCC supports powerpc-darwin9 (and actually powerpc using Rosetta on
darwin10) up to and including current trunk (GCC-14). The only
constraint is the compiler used to bootstrap the build.
Iff you want to build GCC with the last released xcode (3.1.4) for
Darwin9 [MacOSX 10.5] then you will need to stick with GCC10.x as the
last version (newer GCC now needs C++11 to bootstrap, which is not
supported by xcode 3.1.4).
However, once you have a suitable bootstrap compiler [GCC 5 or newer]
you can use that to build any current version of GCC.
I publish branches with some “go faster stripes” for MacOSX / Darwin
(but for powerpc darwin, the upstream branches should also be fine).
