There's an efficient one by Gerardo Ballabio supporting mpz, mpq and
mpf
        http://www.sissa.it/~ballabio/gmp++.html

Others have been mentioned on the address@hidden list.  Some higher
level libraries like NTL, LiDIA and CLN have options to use gmp too.

I've been having a bit of a go at a printf, but it's a distance away
from pretending to work properly.

Personally I'm in favour of something that can mix double and mpf_t in
one printf, so it'd be %e with an extra type letter, maybe F or maybe
a whole MPF or something.
