I've reproduced the hang doing "make clean all CPU_TARGET=i386
OS_TARGET=win32 OPT="-Cp80486 -Op80486"" on my x86_64-win64 machine.
So far I haven't found the bad commit - this problem has been here a while.

I still haven't found the bad commit!

Indeed. This is clearly an issue related to optimizations. The
important point missing here is that it happens when compiling with
ppc1.exe. I just tried building a trunk compiler (make rtl_all
compiler_all) with "OPT=-O- -Cp80486 -Op80486" and then started
another compilation round with compiler built this way, but using -O2
this time, in order to make sure that it wasn't an optimization bug
in the released 3.2.2 compiler. The new compilation round (using a
non-optimized compiler) hangs at an exactly the same place, i.e. it's
a bug (probably endless loop?) in the optimization code specific to
the trunk compiler. @Gareth, could you please have a look at it?
