[Fred J. Tydeman]

Anyone know of any implementations that use SIGFPE?
If so, how is it used?

#include <limits.h>

int main(void)
{
int a = INT_MIN, b = -1;
return a / b;
}

Oops. I see I asked the wrong question.

Anyone know of any implementations where the standard library functions use SIGFPE?
If so, how is it used?

...

"... the functions in <math.h> ... Each function shall execute as if it
were a single operation without raising SIGFPE ..." (7.12.1p1).
