Description David Binderman 2005-06-30 05:59:11 EDT
Description of problem:

I just tried to compile package gnomemeeting-1.2.1-1 from Redhat
Fedora Core development tree with the gcc 4.0.0 compiler and
the compiler flag -Wall.

The compiler said

sound_handling.cpp:486: warning: operation on 'nbr_opened_channels' may be undefined

The source code is

  nbr_opened_channels = PMAX (nbr_opened_channels--, 0);

I agree with the compiler. Suggest avoid post decrement on macro
parameters.
