Hello,
this is <http://bugs.debian.org/561475>. Debian/unstable has recently
switched to gcc-4.4. This seems to have caused a build-failure for
libgcrypt.

Subject: Bug#561475: libgcrypt11/mips(el): FTBFS with gcc-4.4
Package: libgcrypt11
Version: 1.4.1-1
Severity: serious
Tags: patch
Justification: fails to build 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=libgcrypt11&arch=mipsel&ver=1.4.5-1&stamp=1260977092&file=log&as=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 have a look at:
http://gcc.gnu.org/gcc-4.4/changes.html
The patch below fixes the problem by implementing the solution
recommended by the previous web page. With it libgcrypt11 builds
successfully.
