unused-cast-warning for void-casts?

[Martin]

Hi,

due to
https://github.com/danmar/cppcheck/commit/850ad0fed97839ff48a187a30dd1c06b5972d873
now a huge number of issues occurs in our code regarding "unused casts".

Although the checker is correct for these cases:

static_cast<void>(param);
(void)param;

I wonder if it makes sense to warn for them. Casting unused parameters to void is quite common practice I would say, see f.e. https://stackoverflow.com/questions/4647665/why-cast-an-unused-function-parameter-value-to-void

Maybe if the type is 'void' then the checker could bailout?

Best regards,
Martin
