The current status is that the C++ committee appears to be demanding for
such a functionality, but it's mostly a volunteer organization, and the
current proposals for this functionality have been rejected (on the C++
API aspects).  So it's "only" missing a volunteer to draft something
with a higher acceptance probability.  If nothing acceptable gets
proposed, nothing will happen.  At least this is my understanding of
the current status.

Of course if something like this was standardized, it's highly probable
that the GCC implementation would use GMP/MPFR underneath.

As far as C++ is concerned, such a type would belong to the library, it
would not be a new language built-in type.
