re comment #11:

Furtunately, gcc does not warn if you cast the unused variable to (void).
Either most of the users use gcc or many other compilers do it like this (or
don't warn at all?). But casting to void (as it is now) was in the code
already. This 'patch' only moves the casting into a define, which gives us a)
cleaner code and b) the possibility to adopt to other compilers.
Unfortunately, type information is not included...

The downside to your approach is that the statement (if not optimized away)
generates code, while '(void)arg;' doesn't (even with '-O0' for gcc).

If you want to change it, though, the places to change are now easy to find
;-)

Closing this as done, as I didn't find more appearences.
