yeah. The rip thing is fixed for sigcontext in linux.c, but not in this:
// VX32 CPU state
struct vxcpu {
	uint32_t	reg[8];
	uint32_t	eip;
	uint32_t	eflags;

	uint32_t	traperr;
	uint32_t	trapva;  // cr2
};


So the #defines in libvx32/linux.c fix things for sigcontext and break
things for vxcpu struct.

Hmm.

It's rather sleazy but I put
#undef eip
at linux.c line 252 and it builds. Now I get a link error:

more as I hit it. This is a little bit easier than building lguest
modules. Ah, this is going to be fun!

I just shorted vmware. I'm gonna be rich, I tell you! Rich!
