[Python-checkins] CVS: python/dist/src/Modules signalmodule.c,2.56,2.57

[Guido van Rossum]

Update of /cvsroot/python/python/dist/src/Modules
In directory slayer.i.sourceforge.net:/tmp/cvs-serv9822/Modules

Modified Files:
	signalmodule.c 
Log Message:
Make better use of GNU Pth -- patch by Andy Dustman.
I can't test this, so I'm just checking it in with blind faith in Andy.
I've tested that it doesn't broeak a non-Pth build on Linux.

Changes include:

- There's a --with-pth configure option.

- Instead of _GNU_PTH, we test for HAVE_PTH.

- Better signal handling.

- (The config.h.in file is regenerated in a slightly different order.)
