Since current system supply code must not are already working with these identifiers, it wouldn't be affected when C implementations started out supporting these extensions into the programming language.

Loads of new discussion on this “board” concerns Make concerns with various compilers and platforms. Admittedly the makefile A part of the mpfrc++ supply tree is only the most simple, the only targets, for instance, staying static libraries.
