I ran into this again on my next clean build, so I guess it
wasn't just driver error.

Try this after configuring a cross gcc:
   egrep "STMP_FIXPROTO =|Don't run fix" */*/build-gcc/gcc/Makefile

On architectures I can build, I see e.g.

ppc-405-linux/gcc-3.3-glibc-2.2.5/build-gcc/gcc/Makefile:STMP_FIXPROTO =
stmp-fixproto
ppc-405-linux/gcc-3.3-glibc-2.2.5/build-gcc/gcc/Makefile:# Don't run fixproto
ppc-405-linux/gcc-3.3-glibc-2.2.5/build-gcc/gcc/Makefile:STMP_FIXPROTO =

On sh4, which fails with the current bug, I see e.g.
sh4-linux/gcc-3.3-glibc-2.2.5/build-gcc/gcc/Makefile:STMP_FIXPROTO = stmp-fixproto

So, where's that "Don't run fixproto" come from?

$ find . -type f | xargs grep "
./gcc/ChangeLog.4:      * config/i386/x-beos (STMP_FIXPROTO): Don't run fixproto.
./gcc/config/t-freebsd:# Don't run fixproto
./gcc/config/t-interix:# Don't run fixproto
./gcc/config/t-linux:# Don't run fixproto
./gcc/config/t-linux-aout:# Don't run fixproto
./gcc/config/t-netbsd:# Don't run fixproto
./gcc/config/t-openbsd:# Don't run fixproto
./gcc/config/cris/t-cris:# Don't run fixproto
./gcc/config/i386/t-beos:# Don't run fixproto
./gcc/config/i386/t-cygwin:# Don't run fixproto
./gcc/config/xtensa/t-xtensa:# Don't run fixproto

That's as far as I've gotten.  I don't really understand
the gcc/config files, but it seems this is where the problem may lie.

Can anyone shed some light on what's going on here?

Thanks,
Dan
