For what it's worth, IIRC the non-constant initializer used by
MPZ_ROINIT_N has been supported by gcc more or less forever, at least
since 2.3 from the mid 1990s. And it would make some sense to me to
require c99 or gcc.

If we want to do that, I think we should have a separate macro for the
initializer (and preferably point to some shared read-only limb). Or
make mpz_init inline?
