Hm, interesting --- I copied that write_stderr() macro from psql/common.c
and figured it was good. But now that I look, only the uses of it in the
Windows code path there are straightforward; on the Unix side we have
rc = write_stderr("Cancel request sent\n");
(void) rc; /* ignore errors, nothing we can do here */
which evidently was done to shut up exactly this type of overly-nannyish
warning. I'm thinking we need to hide that dead-chicken-waving in the
macro itself. Will deal with it tomorrow.
