I got the testsuite perform fine with TEST_OPT=-O2.

However, I could not build a working optimized compiler, neither could I 
get cycle working. It builds ppc1 and ppc2, but after the
'make FPC=.../ppc2 OLDFPC=.../ppc1 next' command, on Windows it hangs 
for several minutes and then presumably gets killed by timeout 
('Interrupt/exception 0xc00000fd', I observe such behavior for the first 
time), and on Linux it reports Internal Error 2004121202.

But it seems to me that this crap is not related to the issue, but is 
caused by my environment. I'll revert everything, restart in a clean 
way, and then report more.
