GCC also has a variable attribute "unused" (available at least since
the 3-series) that does the trick, though not as cleanly of course.
Seems like GCC 3.x doesn't allow unnamed parameters[1], so if that's a
concern the attribute would be a better choice.

[1] With '-Wall -Wunused-parameter' for both 3.3 and 3.4 I get this:
wtest.c: In function `foo':
wtest.c:2: error: parameter name omitted
