It's just a simple, portable way to make the `unused parameter`
warning shut up, when you're deliberately ignoring your parameters.
There are other ways [__attribute__(( unused )), etc] but they cease
to be simple or portable fairly quickly.

HI, list,
i don't understand why glsl source have so many 'cast to void'
operations, like this.
ir_rvalue *
ast_node::hir(exec_list *instructions,
struct _mesa_glsl_parse_state *state)
{
(void) instructions;
(void) state;
return NULL;
}
i think it's totally void operatio
