Hi!

I've got trouble cross compiling SDL2 with the latest and greatest gcc, 
binutils and mingw-w64.

gcc version 5.1.0 (GCC)
GNU ld (GNU Binutils) 2.25
and mingw-w64 v4.x (from git)

I don't what is to blame. But I'm pretty sure the cross compiler it self 
is in good shape, since I can cross compile SDL1 without any issues.

This is what SDL2 gives me:

I've tried both the latest SDL2 release (2.0.3) and the latest from 
mercurial.

Any hints?
