Message 63295 - Python tracker

Martin, thanks for supporting the idea.

I'm attaching a patch. It is against rev 61255, py3k branch.
It patches configure, configure.in, Modules/signalmodule.c and pyconfig.h.in
I wasn't sure if I should attach a diff for each file, so they are all
packed in the same diff. Also, I wasn't sure if I should append the 
"configure" diff, but I did.

Documentation in "Doc/" and tests aren't done yet, if someone want to
pick this task, please say it.
