This patch uses diagnostic control pragmas to disable some
division-by-zero warnings in stdio-common/tst-unlockedio.c. This is
another test where disabling warnings using diagnostic pragmas seems
appropriate (the warnings are not wildly inappropriate for what the
test deliberately does; the deliberate use of unusual arguments to the
macros being tested means that changing the arguments in a way that
avoids the warning would also unduly perturb what is being tested).
Tested for x86_64.
* stdio-common/tst-unlockedio.c: Include <libc-internal.h>.
(do_test): Disable -Wdiv-by-zero around some calls to
fwrite_unlocked and fread_unlocked.

* libio/bits/stdio.h (fread_unlocked): Cast 0 to (size_t).
(fwrite_unlocked): When checking if size * n is <= 8, cast each
argument to size_t individually. Cast n to (void) instead of
(size_t), surround with (), return (size_t) 0 if one of n or size
is 0. [BZ #316]
* stdio-common/Makefile (tests): Add tst-unlockedio.
* stdio-common/tst-unlockedio.c: New test.
