Same warning here with gcc v4.4.7 in Gentoo too.

python_msgobj.c:529: warning: dereferencing type-punned pointer will break
strict-aliasing rules
python_msgobj.c:529: warning: dereferencing pointer 'MSGtype.395' does
break strict-aliasing rules

Commit 1abde923ee3cbdcce69b72d223fb0c487b892b6e by Daniel seem to not fix
the warning.

I know QA Gentoo complains about it, may exhibit random runtime failures.
We can live with it :) just a compiler warning. It compiles fine. (it's a
matter of disabling strict_aliasing in Makefile (-O2 implies
-fstrict-aliasing)).
