then, there's a bunch of lines as the last one. it seems the directives 
starting with %x are not handled correctly on the lines starting with "int" 
would understand them no ? well, i only need it to compile ok so the user 
will have it... the source of the soft is released at 
http://freshmeat.net/projects/cpp2html/

So if someone's willing to help on it to compile properly... the author seems 
to have abandonned it and i can't reach by mail... Anyone please ?

Thanks
