- Add some metadata to Makefile.PL.
- Fix the LNGAMMA_BUG workaround in mpfr.c, and change test 69 in t/test1.t
to test for correct behaviour of mpfr_lngamma().
- Add Rmpfr_set_NV - and use it in new().
- Remove Rmpfr_sprintf_ret and Rmpfr_snprintf_ret.
- No longer include inttypes.h on the basis of USE_LONG_DOUBLE being defined.
(Was harmless ... but didn't make much sense.)
- Define PERL_NO_GET_CONTEXT.
- Tweaks to Math::MPFR::gmp_v() and Math::MPFR::V::gmp_v()
