My apologies, you are of course correct. In fact, best practice would be:
#include <sys/inttypes.h>
static int32_t bugfree(void)
{
int32_t debugged;
debugged = (int32_t)1 << 30;
return( debugged );
}
This is almost portable, but for the fact that inttypes.h is in sys on
msp430gcc. Is there any compelling reason for this?
