       cccc-3.pre39: Parser errors
 Date: 
       Tue, 23 May 2000 09:23:16 +0200 (MET DST)
Hi,

I have just played around a bit with cccc-3.pre39 and tried
to analyze a large body of C++ code with it. It worked quite
well, and the results look quite useful.

The parser emits, however, a number of syntax errors, which I could
track to a few specific code constructs. These constructs are
legal C/C++, but the cccc parser generates "syntax error" messages.

I have stripped down the problems to the constructs in question;
I enclose a small test program which exhibits all of them. I hope
this is useful for fixing this.
