I'm rather sick of seeing this warnings on all compiles, so I propose we enable the -Wno-unused-results option. I judge that most of the cases where this occurs are error reporting functions, where not much with return code can be done. Can't we try to fix the warnings instead of turning them off? Or is it possible to only turn off these warnings on a specific function?

It strikes me as excessively ugly. (see below)

Modules/faulthandler.c emits a lot of such compiler warning, but there is nothing interesting to do on write() error. I tried to turn off the warning on an instruction using (void)write(...), but gcc doesn't understand that I don't care of write() result here.

You have actually have an assignment, like x = write().
