I'd like to include this. I've now pushed this change to the master repository, so it will be included in the next (upcoming) mingwrt/w32api release. On a somewhat related note, there _is_ actually a defect in the MinGW implementation of -Wformat validation, for the __mingw_printf__ format class; as I've noted on the ticket, it affects the "%hhn" conversion specification, which, although fully supported by the underlying MinGW printf implementation, is rejected by -Wformat validation, resulting in an unhelpfully obtuse diagnostic message — as I discovered by running the mingwrt test-suite with -Wall included in the CFLAGS. Fixing this is trivial, but does require a tedious GCC rebuild, which I now have in hand. -- Regards, Keith.
