just a heads up:

it seems that the libc on interix is built with a compiler that has 64 bit long 
doubles (so it can be none of the bundled compilers, as they all have 12 byte 
long doubles). i'm now looking into patching gcc once more, to have 8 byte long 
doubles too. then all should return back to working.
