I think that doesn't work well because
gcc __attribute__((format(printf, x, y)))
verification fails. It's also possible
to confuse it with printf's own 'h' /
integer precision use.
$ cat h.c
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char** argv)
{
printf("%h02u\n", 1);
return 0;
}
$ gcc h.c
h.c: In function ‘main’:
h.c:6:3: warning: unknown conversion type character ‘0’ in format [-Wformat]
