Summary: Carbon.FSSpec.as_pathname() crashes

Initial Comment:
There's something peculiar in the land of bgen-ed wrappers:

$ ./python.exe 
Python 2.5a0 (#1, Jul 11 2005, 13:21:11) 
[GCC 3.3 20030304 (Apple Computer, Inc. build 1671)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import Carbon.File
[45313 refs]
>>> Carbon.File.FSSpec(os.curdir).as_pathname()    
Segmentation fault

("make test" also crashes).

This is on 10.3.9.

My first investigations with gdb didn't reveal anything that made 
much sense, so it *might* be a compiler bug.  At any rate, it didn't 
do this a few weeks ago...

Argh! It turns out that patch #1035255 was incomplete: it patched 
_Filemodule.c, but not filesupport.py (bad Bob, no cookie:-)

So, when I regenerated _Filemodule.c last week FSSpec.as_pathname() 
still called FSSpec_as_pathname, in stead of _FSSpec_as_pathname 
(note the subtle difference, which I consequently overlooked). This 
resulted in an infinite loop.

Fixed in _Filemodule.c rev. 1.25, filesupport.py rev. 1.22.

The problem appears to be in as_pathname(). Investigating...
