Fix a failure that was only apparent on big-endian machines:

the argument corresponding to 'c' in PyArg_ParseTuple() must be an int,
not a char!  (This is new -- Walter Doerwald changed it in r56044.
Note sure this was a good idea.)

Also removed a debug printf() call that was causing compiler warnings.
