Synopsis: div-by-0 warnings

Responsible-Changed-From-To: unassigned->neil
Responsible-Changed-By: neil
Responsible-Changed-When: Thu Oct 25 23:31:32 2001
Responsible-Changed-Why:
    Tis mine.
State-Changed-From-To: analyzed->closed
State-Changed-By: neil
State-Changed-When: Thu Oct 25 23:31:32 2001
State-Changed-Why:
    Fixed in 3.1 for integer division by zero in C.
    No warning is emitted for floating point div by zero, since
    this can be used to get NaNs and infinities.
    C++ has existing slightly worse semantics; I hope to bring
    those in line with the C front end sometime.
