[Vladimir Marangozov]

Update of /cvsroot/python/python/dist/src
In directory slayer.i.sourceforge.net:/tmp/cvs-serv794

Modified Files:
	configure 
Log Message:
Second try: checks whether right shift extends the sign bit. 

Adds caching and reverts back the 'return' to 'exit()' in 
AC_TRY_RUN as recommended by the Autoconf documentation.
