The change requests which Ken was refering to *were* written against
the compiler - I see no reason to think that the profile would be so
dissimilar.

Ken was wrong when he said "majority". He should have said "vast
majority". But if you want specific numbers, lets say that 97% of
our tests to demonstrate compiler errors are both small and non-
proprietary. (I give myself a 2% margin of error for this estimate).
And while I'm at it, I should also define "small". Our small examples
are generally between 5 and 300 lines of Ada code. And most (lets 
say 70%) of these are less than 50 lines.
