I some projects I'm involved with there's quite a bit of the following:

$ cat int.c
#include <stdio.h>
int
main(void)
{
	int32_t i = 32;
	printf("%d", i);
	return 0;
}
$ gcc -c -Wall int.c
int.c: In function `main':
int.c:6: warning: int format, int32_t arg (arg 2)
int.c:6: warning: int format, int32_t arg (arg 2)

What should the format specifier be to not have that warning
on neither Cygwin nor Linux? (or anywhere for that matter)
If the portable thing to do is casting all printf arguments,
I'm not sure the remedy is worth the damage. But all those
warnings are definitely an annoyance...

In short, I for one would be very glad to see "typedef int
int32_t" (but I'm not a g++ user).

Cheers,
Peter
