0.03
 - Remove 'not' from overloads. Apparently achieved nothing anyway, and 5.16
   warns that it's invalid.
 - Add MPFI_VERSION_MAJOR, MPFI_VERSION_MAJOR, MPFI_VERSION_PATCHLEVEL
   and MPFI_VERSION_STRING (mpfi-1.5.1 and later only).
 - In aab_basic.t, check that library and header versions match
   (mpfi-1.5.1 and later only).

0.02
 - Add documentation of gmp_v and mpfr_v (previously missed).
 - In aab_basic.t print out the mpfr and mpc library versions being
   used, as reported by the library in use.
 - In MPFI.xs change mpfr_v() to return the library version instead
   of the mpfr header version (as had previously been the case).
 - Minor doc fix.

0.01
 - First release.
