[PATCH] make SPARC, GCC-3.1, ieee_double_extract, and mpfr play together

[Nix]

The preprocessor symbol for SPARC has changed in GCC 3.1, breaking
IEEE float unions and thus mpfr on SPARC.

This fixes that; mpfr passes all its tests with that done (as does GMP
as a whole). Without it, configure warns that the ieee_double_extract is
not defined, and mpfr fails to build.

main ChangeLog:

2002-07-14  Nix  <address@hidden>

        * gmp-impl.h (union ieee_double_extract): Add __sparc__.

mpfr/ ChangeLog:

2002-07-14  Nix  <address@hidden>

        * mpfr-math.h: Add __sparc__.
