Thanks.

I was surprised, too, but then I read that 'while' is explicitly
excluded from the warning:

    `-Wempty-body'
         Warn if an empty body occurs in an `if', `else' or `do while'
         statement.  This warning is also enabled by `-Wextra'.

Pedro> FAOD, this is fine with me.

Thanks.  I'm going to wait for more comments.
