Well, it seems to me that it should be part of the mangling if and only
if it is also a factor in overloading.  Since C++ doesn't yet support
restrict, we don't have a definitive resolution of the latter.  So, unless
we want to specify it ourselves, and I think that would be very premature,
the answer is up in the air.

Perhaps we should just clarify in the document that it is specified for
use IF restrict enters into overloading decisions, and should be
omitted otherwise, without specifying the choice.  In effect, its use
becomes implementation-specific, as is the overloading effect of the
non-standard restrict qualifier.

Comments?
