Hi John,

I believe I've fixed this now, here is the ChangeLog:

 * fixed bug reported by john o goyo <address@hidden>.
   (testsuite/gm2/pim/run/pass/Countdown.mod)
 * for loops are now implemented as per ISO description.
   GNU Modula-2 now calculates the last iteration value
   before the start of a loop. It then initializes the
   iteration value and works towards the final value,
   rather than testing to see whether the iteration value
   exceeds or preceeds the limit value (which failed when using
   a CARDINAL iterator and stopping at 0).
 * added a number of run tests to exercise these changes.

The cvs changes are being uploaded, should be ready in an hours time..
Thanks for the report, if you have time please test again,

regards,
Gaius
