Does Windows even support the large code model?

That's PA-RISC, not x86-64.  But may I ask why you went to such great 
lengths to find anything about the large code model on x86-64?  What's 
your usecase?

I'm not sure if the README or other documentation should specify 
unsupported things as that list is unlimited.  The normal course of action 
would be to document supported features, implying that everything not 
mentioned can't be expected to be supported.  (Of course, TCCs current 
docu hasn't reached that ideal yet either).


Ciao,
