Hello I have several questions: 1. Is there a list of known warnings and errors generated from the GCC on the web? I mean a list that would shortly explain the reason for it. Something like MSDN - heaven forbids!!! :-). 2. I get an annoying warning message - "warning: too many arguments for format". What does it mean? 3. Good programing parctice - If I have a static global variable, that is defined in one file, but not used in it - why is it a bad thing (I get a warning)? Thanks a lot and have a good weekend Eitan Gur
