Hi everyone,

I have started using g++ with the -Wall option which gives me lots of useful
warnings (e.g., about missing cases in switch statements if the variable at
hand is an enum type, or about unused variables). Doing this, however, I get
*many* warnings regarding the LEDA header files (see bottom of mail). This
makes it pretty hard to find the interesting warnings about my own code. I
would appreciate very much a re-write of the header files such that g++ does
not complain anymore if the -Wall option is used. I was able, with minor
changes to reduce the warnings quite a bit, but probably the LEDA authors are
more qualified to do this. Any comments?

Regards,
Bernd

P.S.: a small excerpt of the warnings:
