Hi,

I'm having trouble compiling the code below with GCC v3.1
under DJGPP. I currently have no other systems available
(with v3.1) so I would like to ask DJGPP folks first before 
posting this on a GCC mailing list.
The code compiles nicely with all other versions of GCC I have
here (2.95.2, 2.95.3 3.0.2, 3.0.3, 3.0.4).
I'm not so fluent with the C++ standard, so there might be something
wrong with the code. The code given here doesn't actually do
anything useful, but this is more or less the shortest example
that shows this problem which I got out of a much more complex
program.

Any ideas welcome.

Regards,

Tony
