- I recently posted a message asking if anyone had sucessfully compiled
- mawk on the 3B1/7300/UNIXPC machine. I received no responses, so I
- am following up with a more specific question.
-
- Is there some (as far as I can tell, undocumented) method for turning on
- floating point exception trapping for normal math operations so that
- division by zero, overflow, underflow, etc. will generate a SIGFPE (or
- can be trapped by some other mechanism)? If so, could you provide the
- necessary details.
-
- This is for the 3B1 machine running version 3.51m of the OS.
-
- Thanks for any help you may be able to offer.
