+ Add mpfr_add1sp which provides addition when all the operands have the same precision.
+ Add new test files for mpfr_copysign and mpfr_min and mpfr_max. + Add test for mpfr_exp10 in tests/texp.c + Improve coverage of div_2ui.c and mul_2ui.c + Add a forgotten ASSERT in mpfr_sqrt git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@2686 280ebfd0-de03-0410-8827-d642c229c3f4
