For instance Comeau C++ compiler with option --strict and (IIRC,
but I don't have it handy at the moment) Intel's icc compiler
with the -Xc option (select strict ANSI C/C++ conformance dialect).
However, the point is that the code I have indicated violates the
standard;  as C++ compiler are moving more and more towards standard
conformance the problem may show up at any time with any compiler.

You are right of course (indeed I was expecting Gerardo, as the father,
of the C++ interface, would elaborate on the idea so as to suit his taste).
I will provide a better patch at the soonest (since I really hope it could
be incorporated in the next GMP's release).
All the best
