Yup, I can reproduce this.

Seems like a bug in gcc.  We don't normally handle bugs in
upstream products, we just package them.  The reporter might
like to see if it has been reported upstream
(http://gcc.gnu.org/bugzilla/).

This should be fixed with mingw32-binutils-2.20.1-2.fc14 which enables ld's
auto-import option by default. Can you confirm the fix?

Yes, that seems to have fixed my simple test app and the more complicated one
that I stripped down to make the simple one.
