>Description:
        When generating a lexer (actually from lilypond-2.2.0)
        using "%option c++" and "option debug" I got a C++ syntax
        error because the generated code used "std:endl" instead
        of "std::endl".
	Probably introduced by last commit which was:

	date: 2003/11/18 21:37:39;  author: christos;  state: Exp;  lines: +7 -7
	More g++-3 fixes:
        	- std:c{in,out,err}
       		- include <iostream>
        	- use std::endl instead of \n

>How-To-Repeat:
        Looks like this is only triggered with both %option c++
        and %option debug.
>Fix:
        The fix is trivial:
