Got this at trying to build gcc-9.3.0-r1 on my G4 DP. Tried to build a 2nd time and got exactly the same error.

I tried to work through https://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide but failed to replicate the command as I only got "/var/tmp/portage/sys-devel/gcc-9.3.0-r1/work/gcc-9.3.0/gcc/ggc-page.c:20:10: fatal error: config.h: No such file or directory" executing the command out from /var/tmp/portage/sys-devel/gcc-9.3.0-r1/work/build.

I backed up gcc's build directory just in case.

if you're hitting this with a modern GCC (e.g. 9.4.0, but ideally a newer branch), let us know?

Didn't encounter gcc build problems meanwhile on ppc.

Atm I am chasing a kernel bug which happens during longer builds (https://bugzilla.kernel.org/show_bug.cgi?id=215389). Building/testing gcc natively on the G4 makes sense again, if anything, when this one gets fixed.
