Yes, this!  Try to (!) never change committed testcase souces, however 
invalid they may be (changing how they are compiled, including by 
introducing new dg-directives and using them in comments, is of course 
okay).

(And FWIW: I'm fine with Florians proposal.  I personally think the 
arguments for upgrading the warnings to errors are _not_ strong enough, 
but I don't think so very strongly :) )


Ciao,
Michael.
