State-Changed-Why:
    No feedback for six months, and the existing behavior is probably correct anyway.

State-Changed-When: Wed Jun 26 12:57:57 2002
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.

>Description:
	libg2c/libF77/configure unconditionally emits the IEEE_COMPLEX_DIVIDE
	define.  Since the VAX doesn't have IEEE math, IEEE_COMPLEX_DIVIDE
	should not be emitted.
>How-To-Repeat:
	run libg2c/libF77/configure with a vax target.
>Fix:
	Only emit IEEE_COMPLEX_DIVIDE if the target actually uses IEEE math.
