Hello,

I compile most of my code with gcc -Wall. Unfortunately I use either sccs
or rcs and I like to keep an sccs or rcs string as:

#ifndef lint
static char rcsid[] = "$Id$";
#endif

Unfortunately there is no way I know of to tell gcc that 
I know that this variable is not used and I don't care! How do other 
people avoid this warning? I know that I could say:

#ifndef __GNUC__
...

but then the strings are not compiled in the code...

I wish that there was a:

#pragma notused 

or something along those lines...
