I just ran the same program here on various things (sparc,
meiko sparc-hosted, mips).  Here are the results of the Kent
jury...

(t800) mcc txxx.c ; mrun m.out

The Expected Results:> free_l[1]=-0.000002 and free_l[2]=0.000007
The Calculated Values:> free_l[1]=0.000031 and free_l[2]=-0.000118
Done...
