Hi there,
I've found some trivial bugs in the subject, or at least I think so.
There's not too much to say, see the diffs below. Only one thing: my
Linux machine segfaulted on the commands `mkid' and `xtokid', when the
`strtok' library routine tried to chop up the string pointed to by the
static variable `dot'. I suppose the string literal "." was put into
a read-only memory segment; counterface the `-Wwrite-strings' compiler
option of gcc. As `strtok' comes to writing the string, it causes
problems. While `lid' did not segfault, it still seemed to be a good
move for me to change the similar code in `lid.c', too.
I think my modification to `lid.c' in lines 761--765 doesn't solve the
problem with the `search_flinkv' function, but not even understanding
what it does I'd rather leave its further investigation to you...
Cheers: Feri.
