Could you send the intermediate files directly to me via email so I can
check out the differences. The wf_acos.i output I got by using -save-temps
for the fragment of code that I expected to have the problem  is as
follows:-

# 22 "wf_acos.c" 2
        float acosf(x)
        float x;
{
        _float_long_union ux;

        ux.f = x;

        float z;
        z = __ieee754_acosf(x);
        if(__fdlib_version == __fdlibm_ieee || (((*(long *)&(ux.l) &
0x7f800000L)==0x7f800000L) && ((*(long *)&(ux.l) &
0x007fffffL)!=0000000000L))) return z;
        if(fabsf(x)>(float)1.0) {

                return (float)__kernel_standard((double)x,(double)x,101);
        } else
            return z;

}


Thanks,
