[Bf-committers] unused function args & warnings.

Dear Campbell,

The idea is IMHO good. I usually handle warnings like errors, because 
many times the warning give a reasonable hint for a possible bug.

If portability is an important issue something like 

#define UNUSED(x) (void)x

and placing the definitions in the function body may be better, 
because __attribute__ is not a common feature of all C compilers 
which may be used to compile Blender.
