Geoff, do you have any patch to completely disable PCH during bootstrap? At
least that would be a check if it's PCH related or not. If you look in the
audit trail of the bug, you will see two different patches that I tried to
apply without success. I was thinking it's PCH related because the bug
requires the "-x" parameter on the command line to show up.

Besides, I was able to bootstrap cygwin with no problems till two weeks ago.
Can you think of any patches in this timeframe that might have
caused/uncovered this problem?
