-Wconversion does this, in newer versions of gcc.
Interesting. It could well be my mistake, but shouldn't "gcc
-Wconversion test.c" throw at least some unhappiness with:
#include <stdio.h>
int main(void){
int i=99999;
short s;
s=i;
printf("s is %d\n", s);
return 0;
}
It does just that, with *newer* versions of GCC -- 4.2.0 doesn't
yet do this, you need an unreleased version right now.
