Well, my patch as it is does not lead to warning messages.  Only if you
omit the cast operations in the line after the FIXME comment you would get
warnings when compiling with -Wall -W.

Without my patch, I still was getting warning messages when compiling with
-Wall and -W, although I don't remember what kind of warning it was.  My
version of gcc is "2.95.3".
