Uh, it's been a generic arithmetic error signal for a long time, like
ENOTTY complaining about generic wrong-type-of-file-descriptor situations.
I was surprised by that a couple of years ago.
SIGFPE A Erroneous arithmetic operation.
SIGFPE FPE_INTDIV Integer divide by zero.
FPE_INTOVF Integer overflow.
FPE_FLTDIV Floating-point divide by zero.
Now, if the hardware in question can't create SIGFPE on integer divide,
I don't think we should torture the compiler into simulating it.
