This case should be closed. I don't think that the bug has been caused
by my patch. Right after my patch merging PCH was been done. Also
there were a lot of other patches committed during several days before
the bug was been reported.
In any case, I've checked bootstrap of gcc as of Feb 4 under cygwin and
found that the bug had been gone.
