Right, that makes sense, thanks for the explanations. As someone with
very little x86 experience (zero experience from this perspective)
it's kind of daunting that I'd have to refactor all this stuff. All
these helpers via macros to get around C's 'minimalism' also seem like
something I'd have to

Ah so they modify it? If so it could surely be worked around with
explicit
