My first try to build gcc-3.4.0 was with the latest available gcc for cygwin,
which is gcc-3.3.1, but -O2 instead of -O3. Note that this works fine.  Then I
tried to bootstrap again with the newly created gcc-3.4.0 as system compiler,
but now with -O3, then I get the failure even before the first stage when the
system gcc is used to compile the ada files.  The third try was to reinstall the
old gcc-3.3.1 to run the bootstrap, again with -O3 all over the place, then I
got the same error, but now in stage1 (the problem reported here).

It seems that it is not possible to run the bootstrap with -O3 on Cygwin.

I'll run the bootstrap now with exactly the same flags but -O2 instead of -O3
and report then after stage1 is completed (or is not completed).
