Also, if you use a recent enough version of gcc, ./configure will disable the warning. I would prefer if stop using these kinds of hacks. Do you mean (void)write(...)? Many people think this is good practice, since it indicates to the reader that the return value is deliberately ignored.
Unfortunately (void) write(...) does not get rid of the warning.
Asking me to change the version of the compiler i'm using is unfortunately not helpful. I don't want to see this warning on any common default compiler versions today.
I am not going to use a different gcc/g++ version than what my distro provides to build python unless we start making that demand of all CPython users as well.
It is normally a useful warning message, just not in this specific case.
