Update of /cvsroot/python/python/dist/src/Mac/Python
In directory usw-pr-cvs1:/tmp/cvs-serv11197/Mac/Python

Modified Files:
	macglue.c 
Log Message:
Split macglue.c into two: a new mactoolboxglue.c (in ./Python)
with functionality needed for both unix-Python and MacPython and a
new smaller ./Mac/Python/macglue.c which contains MacPython stuff only.

pymactoolbox.h has moved to ./Include from ./Mac/Include and now also
contains the relevant stuff from macglue.h.

The net effect of this is that the ./Mac subdirectory is not needed
anymore for building the unix-Python core on MacOSX (it is needed
for building the extension modules).
