DEC Ada for VMS, at least on Alpha, produces a "non-portability"
summary at the end of the listing. I don't know if it gets down
to this level of detail, but that sounds like the right approach
for indicating dependence on a particular implementation.  Of
course this might be viewed by a compiler vendor as having some
negative business impact as well as some positive business impact,
and that probably moves it down a few notches on the priority
scale.
