I thought that MINDOUBLE was the smallest value a double
could hold. Yet when i compile the following program:

#include <values.h>

#include <math.h>

main()
{
        double d1,d2;

        d1 = MINDOUBLE;
        d2 = MAXDOUBLE;

        printf("Min=%lf\nMax=%lf\n",d1,d2);
}

I get a 'constant-out-of-range' warning for the
statement assigning MINDOUBLE to d1, and it prints
out "Min=0.000000".

Actually, cc does this as well (but it doesn't even acknowledge
that MINDOUBLE is out of range), so i'm not certain that
this is really a bug.

This is gcc version 1.37.1, running on a Sparc.
