Update of /cvsroot/python/python/dist/src/Include
In directory slayer.i.sourceforge.net:/tmp/cvs-serv5758/python/dist/src/Include

Modified Files:
	pyport.h 
Log Message:
Move LONG_BIT from intobject.c to pyport.h.  #error if it's already been
#define'd to an unreasonable value (several recent gcc systems have
misdefined it, causing bogus overflows in integer multiplication).  Nuke
CHAR_BIT entirely.
