But this is a bug in py2exe.  Python itself works just fine.  py2exe is 
associating what .py files to bytecode compile based on the imports 
used.  When I changed _ALL_ references that _used_ to have uppercase 
letters to lowercase to match the filenames (the email package switched 
to all lowercase in Python 2.5), the problem went away.  This includes 
the email package itself (i.e. someone switched to lowercase but then 
forgot to modify the email package completely to lowercase).  As far as 
I can tell, this has nothing to do with the OS.

C++ (Safe C++ to be specific).  Or PHP.  Depends on what I'm developing.
