[Vm-dev] VM patches for oop comparison and usqInt declarations

Ok, I was working with Craig a bit on this and I noticed for example.

usqInt endOfMemory;

    sqInt fwdBlock2;

		/* begin restoreHeadersAfterForwardBecome: */
		fwdBlock2 = ((foo->endOfMemory + BaseHeaderSize) + 7) & (WordMask -  
		fwdBlock2 += BytesPerWord * 4;

Really shouldn't one consider that if a unsigned value gets assigned  
to a signed integer one should really consider that a possible problem?

Needless to say I believe the code above won't work as intended.
