Here is a prerelease for mpdecimal:

I think I've addressed all your comments you sent privately earlier.
The "uname -s" in configure.ac is only used for suncc and Darwin.
It should not affect cross building.

I still have to update the docs and a couple of READMEs for the final release.
The code in libmpdec is now the same as on hg.python.org and is highly unlikely
to change.

If you have time and have some final requests for the configury (config.guess,
install-sh?), let me know.  I prefer to run the final tests on the exact tarball
that is ultimately shipped.

The deal for Python-3.3 and Python-3.4 is:  For compatibility with decimal.py
only link against libmpdec.so.2.
