Some are for actual 'debugging' use, calls to be added later, not
just for verbose output.  Others are for verbose output when DEBUG
is defined.  I have it setup so they are always built to do the
syntax check, but removed by the optimizer when not used.  I was
planning to remove these routines sometime in the future, but want
to keep them in until the code gets stable.
