[Python-checkins] python/dist/src configure.in, 1.477, 1.478 configure, 1.464, 1.465

Update of /cvsroot/python/python/dist/src
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv3095

Modified Files:
	configure.in configure 
Log Message:
After discussion on the PythonMac-SIG it was decided that it is better
to make using "-undefined dynamic_lookup" for linking extensions more
automatic on 10.3 and later. So if we're on that platform and
MACOSX_DEPLOYMENT_TARGET is not set we now set it to the current OSX
version during configure. Additionally, distutils will pick up the
configure-time value by default.

Will backport.
