_Files vs __files (&1.4 vs 1.5a3) was: [PYTHONMAC-SIG] Mac SWIG & dynamic loading MacPython modules

That's right: __files is the symbol used by the new MSL C library (which 
Python 1.5 uses, and apparently MacSWIG uses too). _Files is the symbol used 
by the old Plaugher C library. Mixing the two in a program that uses stdio.h 
is impossible, as far as I know.

And if you load the 1.5a3 developers kit (from the same place where you found 
the 1.5a3 distribution) you should be able to compile your example again 
without this error. This is probably a prudent thing to do, because there are 
quite some changes in the Python API...
