At the moment, on OS X /usr/bin/pythonw2.x is a simple sh script 
that exec's a python interpreter within a valid OS X application 
bundle.  The problem is that this prevents python scripts from 
using pythonw in the #! line.  Darwin won't allow a script to act as 
an interpreter in a #! line.

This patch replaces the shell script with a simple C program that 
does the same thing -- it just calls execv on the python interpreter 
within the OS X app bundle.  Since it is a compiled executable it is 
allowed to act as an interpreter in #! lines.

Your patch guidelines said you preferred multiple patches to be 
concatenated in a single file.  My patch consists of a Makefile 
change and a new file, dist/src/Mac/OSX/pythonw.c.  I've included 
both in the text file attached to this report.  It would probably be 
prudent for somebody to review the Makefile change, since it's 
always tricky to find the right way to put a new file in someone 
else's build process.

Thank you,
