On OSX warnings are just warnings but part of my test process involves
grepping the log output for 'warning'. On x86 clang I configure with
--extra-cflags=-Werror, to work around the pragma diagnostic check.
(None of the spurious diagnostics we use the pragma to suppress are in
practice a problem on my build.)
