You're mixing cygwin objects with mingw32. That's a no no.

Huh? What's -lC? There is no -lC for mingw32.

Again, you're mixing cygwin objects/libraries with mingw32.
You say you're using egcs-1.1.1/mingw32, but it looks like you're using
Cygwin gcc in -mno-cygwin mode. Is that true?
If that is so, I've posted many times here on how to get all of this to
work, and I'm not about to repeat it. Get the mingw32 target libraries
from my site and make sure you link with those.

From what you've posted, it looks like a misunderstanding on your part,
but that doesn't preclude a bug of course. Whether it works under Linux
is irrelevant.
