One more thing in this change, I've moved CFLAGS from make onto the ./configure at execution. Y'know what? Scratch that...
This might require rigorous testing I hope... Fixes #1

I tried this locally and I needed this patch:

Otherwise things went smoothly, I tested on the ultralib iQue branch and it seemed to work

Another nit besides the patch posted by cadmic

Suggested change

	#else
	#ifdef DARWIN
	#elif defined(DARWIN)

Would remove the need for an extra trailing #endif
