Well... even that has problems :-)

This seems very odd.  Unresolved external?  Hmm.  I can't figure out where 
this stuff is actually being built to go look at the details.

Trying to see where these files are located, I ran the build again.  
Interestingly, this time it didn't even fiddle with pycryptopp BUT it failed 
to build zfec 1.4.5:

------

Seems like some serious disagreement between the code and Microsoft's compiler 
about what C should look like.  Or a very wrong verions of a zfec header 
file.

I'm not sure what to try next.  I guess I'll go back to 2.5 and the mingw 
compiler.
