If speed is more important than size (likely as most AVR chips today
have much more flash than those available long long ago when that code
was originally written), here ia a proposed (untested) patch to unroll
the loop (simply repeat the code 8 times) for >8K flash devices,
The larger and faster

Is there a test scaffold for the functions from lib1funcs.S,
correctness, size&speed over the variety of 8-bit AVR cores?
Size is the easiest one: Just determine the size of, say
-nodefaultlibs -nostartfiles against a respective comp
