SET DEBUG STATE WHEN TOLD TO SET THE DEBUG STATE

Honestly, this one bug has cost me days of time.  Why the HELL
does setting the debug state NOT WORK.  EVER.  The MAGIC CODE to
figure out whether or not we're in a debugger DOES NOT WORK FOR ME.
The environment variable which FORCES the code to believe that
the debugger attached sets a variable LOCAL TO THE FUNCTION,
and FAILS TO SET THE GLOBAL VARIABLE WHICH SETS THE DEBUG STATE.

<sigh>
