Remove some obsolete code that causes a gcc warning.

Browse source 
In my OpenBSD/amd64 system, the code becomes

    if (0)
        outname.on_valu &= ~(((0xFFFFFFFF)<<32)<<32);

The 0xFFFFFFFF is a 32-bit int, so the left shift by 32 is out of
range and causes the gcc warning.

The intent might be to clear any sign-extended bits, if the assignment
outname.on_valu = valu did sign extension.  Old C had no unsigned
long, so .on_valu would have been long.  The code is obsolete because
h/out.h now declares .on_valu as uint32_t.
