This seemed reasonable and an easy problem to fix so I did a quick
grep for lines with "a character with MSB=1". Attached are the two
trivial patches.
I ignored all comments with Michael T�xen's name in them.
I also stripped and diffed the object files to confirm that the
generated code is identical.
