[cfe-commits] [Patch] Format string warnings should refer to "%zu" etc by typedef type

[Hans Wennborg]

Hi all,

The attached patch changes the warning for

printf("%zu", 42.0);

from "conversion specifies type 'unsigned long'" to "conversion
specifies type 'size_t' (aka 'unsigned long')" if the relevant typedef
is in scope.

Please take a look and let me know if it's ok for me to land.

Thanks,
Hans
