The snapshot 2009-10-02 works but the self-built cygwin does not?

I don't know what gcc cgf is using to generate the snapshots, I just
know he's using a Linux cross compiler.

Personally I'm using a Linux cross gcc "i686-pc-cygwin-gcc (GCC) 4.3.2
20080827 (alpha-testing) 1" which is based on Dave's first gcc-4 release
plus a small patch from cgf necessary for the cross build.  I have no
problems at all running my self-built Cygwin DLLs.  FWIW, I'm usually
not building with optimization for easier debugging.

Right now I'm going to build a normal optimized version to see if that
works for me.

[...time passes...]

Yes, it works.

May I suspect a bug in the latest gcc?
