Package: mpfr
Version: 2.4.2-2
Severity: serious
Tags: patch
Justification: no longer builds from source
mpfr fails to build on mips(el) with gcc-4.4. A full build log can be
found here:
https://buildd.debian.org/fetch.cgi?pkg=mpfrarch=mipselver=2.4.2-2stamp=1260358474file=logas=raw
This is due to a change in GCC 4.4, the h asm constraint is not
supported anymore on mips. For more details please see:
http://gcc.gnu.org/gcc-4.4/changes.html
The patch below fixes the problem by implementing the solution
recommended the previous web page. With it, mpfr builds and
passes the testsuite.
