I note in
http://www-sor.inria.fr/~piumarta/squeak/devel/src/vm/interp.c

int fetchWordofObject(int fieldIndex, int oop) {
	return longAt(((((char *) oop)) + BaseHeaderSize) + (fieldIndex << 2));
}

however this private dated copy of interp.c which contains  
fetchWordofObject is not found in the current build

I'll note to confuse XCode the platform/unix/ tree contains

src
src32
src64

you should delete those directories to avoid confusion, normally this  
is not a problem but I have to
wonder where xcode thinks it is finding your interp.c

If your copy of interp.c then still contains fetchWordofObject then  
something is wrong.
I'll note my copy of interp.c says:
