Dave,
patch below fixes four cases where a s/strtok(/strsep(\&/ is not
sufficient to properly eliminate strtok. The problem arrises
because strsep modifies the pointer it is given while strtok did
not.
The atari file doesn't compile without this patch, because a char
array is mistreated as char pointer. The rest are cases where the
destroyed char pointer is used afterwards.
There may be more errors of that kind, I didn't check (yet). Patch
is untested but should make things "righter". ;)
Ren?
