[Kde-bindings] Problems builing RUBY binding

[Alex Martin Ugalde]

> could you add a #include <stdio.h> line to the c++ file in question?

rubylib/qtruby/Qt.cpp already has this line:
#include <stdio.h>
#include <stdarg.h>

#include <qglobal.h>
#include <qregexp.h>
#include <qstring.h>
#include <qptrdict.h>
#include <qintdict.h>
#include <qapplication.h>
#include <qmetaobject.h>
#include <private/qucomextra_p.h>
