Dyna-C is indeed a derivative Ron Cain's Small-C.  The difference is
that it's also one of the best 6809 Small-C's around.  I have used it
and find that it runs quite fast and produces surprisingly good code.
I have also used Dugger's compiler.  It's just not in the same league as
Dyna-C in my opinion.

I've heard rumors to the effect that M'ware C for the CoCo will be
a full edition, but have not talked to Microware about it.

Getting back to Dyna-C.  I'm pulling these numbers off the top of my
head, so take them as guides and not absolutes.  But here is a quick
comparison of the run time benchmarks for that infamous old standby
PRIMES.

Introl or Microware C:  typically 15 to 17 seconds
Dyna-C:                 around 29 seconds
Dugger C:               50 to 60 seconds

These were done on my homebrew 1Mhz 6809 system
