PATCH: pws-24: unsigned character problems

[Peter Stephenson]

(This is also in another mail queue so could in theory arrive twice.)

The first of these hunks fixes the problem I was having on SunOS 4.1.3_U1
with gcc 2.7.0: itok(c) wasn't working where c was a char, even though itok
is defined with a STOUC() in it.  Changing c to be an int worked.

Coincidentally, I'd already fixed an error message about unsigned chars
from the test I added for spaces in option strings, which is the second
hunk.
