Synopsis: IEEE_COMPLEX_DIVIDE defined on VAX target

State-Changed-Why:
IEEE_COMPLEX_DIVIDE causes the COMPLEX and DOUBLE COMPLEX
divide routines in libf2c to honor the *hardware* treatment
of x/0.0 with x != 0.0. This is the obvious choice when
running on IEEE-754 compliant hardware, but might be a
good choice on VAX too.
Please advice.
Note that complex division is generally expanded inline
by the Fortran front-end, unless -Os is given as a
command line option.
