This is actually a bug in the scripts themselves. It turns out that 
cygwin's /bin/sh is actually ash, not bash. So it doesn't support the 
syntax of  $(($x + 1)) . Instead of giving you 2 it gives 1 + 1. My 
workaround was to close all cygwin shells, and then delete 
c:\cygwin\bin\sh.exe and copy c:\cygwin\bash.exe to sh.exe.

The other workaround would be to figure out how to do addition in pure 
POSIX shell, or go around and make sure all the scripts reference 
/bin/bash instead of /bin/sh.

This should probably be registered as a bug, but I'm not sure what the 
"correct" solution is.

It's a bug in the script, not in the binary.

I forgot to update the wiki. The correct page is:
http://ct.radiology.uiowa.edu/~jfmeinel/tla-short-path/

There should be the latest version of the binary there. I'm using it 
myself, so I'm pretty sure it is good.

Thanks for evaluating it. Sorry all the ends aren't as polished as they 
could be, if you have any suggestions I'm listening. (Especially if the 
suggestions come in patch form :)
