1) The warnings you are getting are from the first parameter.  When I cast
it to AddLNode((void **)&Head, Walker); I don't get any warnings.  Chris Torek
gave you the correct answer.  What made you think the warnings were from the
second parameter?

2) Cross posting to alt.msdos.programmer, comp.lang.c, comp.os.msdos.programmer
usually means too many people are going to see the question and answer.  I'm
leaving the groups, but I suggest followups (if any) by mail.
