need help

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
