Hi all,

I just committed as obvious another pair of accepts-invalid fixes:

Also I would like to thank Vittorio for the large number of bug
reports he has been delivering lately. (I could make a comment about
his great talent for writing invalid Fortran code, but that would
probably sound more negative than intended ;)

In fact, I *do* consider this a virtue - in most cases it will catch errors in the parser or resolver, but there are also those who will lead to (hidden) bugs in later stages of the compiler.


In the days of g77 we had one person who made a program to insert random one-character changes into valid programs until he hit an ICE.

Of course, that was all automated ... it lead to a *lot* of bug fixes.
