  Modified files:
    usr.bin/make         var.c 
  Log:
  Possibly expand the variable name's embedded variables before using it, as
  seen (somewhat) in NetBSD.  This catches a few extra recursion cases that
  could be hidden by expanding a NIL variable causing an existing variable to
  be returned (which caused infinite looping and climbing memory usage in at
  least one case).
