Regression failure for floats

I am seeing the following regression failure for current CVS.  On my OS,
BSD/OS 4.3, it seems once you hit Infinity, you can't negate it. 
/usr/include/math.h has:
/* Generate an overflow to create +Inf; the multiply shuts up gcc 1 */#define HUGE_VAL    (1e250*1e250)       /* IEEE:
positiveinfinity */
 
and our float4in code has:
       else if (strcasecmp(num, "-Infinity") == 0)           val = -HUGE_VAL;

Seems that doesn't work for me.
