With the changes I sent you and using check_assignment_types() for printf_fmt_numtype() I get only 3 warnings in the same drivers, all for trying to print a bitwise type (which should probably be acceptable for the %x format). But yes, checking the signedness will most probably gives a lot of warnings. I think this shouldn't be done without support for the flag '-Wformat-signedness'. -- Luc
