Ah, that's the problem.  The A/D pins wake up as analog inputs.  You need
to explicitly set them to digital I/O if you want to use them that way.

Take a look at my development environment at http://www.embedinc.com/pic.
If you had used it and therefore declared all your I/O pins with the
/INBIT and /OUTBIT preprocessor directives, the standard PORT module would
have initialized them the way you wanted automatically.
