fyi, this is not a problem with egcs, but rather has to do with
the cygwin32 DLL (that's why it works for mingw32 and uwin and
other egcs targets).

I just submitted a patch to cygwin32 developers that fixes this.

That's not true. The problem is that the order of initialization isn't
correct in the current cygwin DLL, so any dependencies cause problems.
