It appears to be a combination of "a" and "c".  Windows Python 2.5 does not 
have an issue with the above file, nor does Cygwin Python 2.3.  Windows 
Python 2.3 and 2.4 do have the problem.


Dunno.  It sounds like the people making these distributions have an 
over-eager MANIFEST.in or an over-eager source control system.  They should 
probably add a MANIFEST.in rule to exclude the files from the source release.
