So how comes that http://minnow.cc.gatech.edu/squeak/2711 (the only source I
have access to) gives me code that looks like the following:

#if VM_PROXY_MINOR > 4
	struct GenericPlugin	*genericPlugin	 ;

	char*		interpreterVersion ;
	int*		atCache;
	int*		iSizeAtCacheAdr ;
[...]

Not what I would expect for a 1.5 proxy. Considering that you wrote:

can you say which ones may have been built against the "normal" vs. the
above 1.5 proxy?

That, I think, still stands to reason.
