Submitted By: Bruce Dubbs <bdubbs_at_linuxfromscratch_dot_org>
Date: 2014-08-04
Initial Package Version: 3.1.2
Upstream Status: Already in upstream patch repo
Origin: Upstream
Description: This patch contains patches for several bugs in MPFR.
Note that the patch for configure.ac has been
removed to prevent unneeded regeneration of build
files.
