Seltsame Fehlermeldung beim compilieren meines FLTK Programms

[Omen777]

Hallo zusammen,

wenn ich mein FLTK Programm mit fltk-config --compile fltk.cpp compilieren möchte
bekomme ich folgende Fehlermeldung:

/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/i486-linux-gnu/bits/c++config.h:43: error: expected unqualified-id before ‘namespace’
/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/i486-linux-gnu/bits/c++config.h:47: error: ‘__gnu_debug_def’ is not a namespace-name
/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/i486-linux-gnu/bits/c++config.h:47: error: expected namespace-name before ‘;’ token

Kann mr jemand sagen woran das liegt und was ich an meinem Programm ändern muss ?!?
Hier mal der Code dazu:

fltk.h

#include <FL/Fl.H>
	#include <FL/Fl_Window.H>
	#include <FL/Fl_Box.H>
	#include<FL/Fl_Check_Button.H>

	#include <FL/Fl_Input.H>
	#include <FL/Fl_Multiline_Input.H>
	#include <FL/Fl_Button.H>
	#include <FL/Fl_Output.H>

	class std_window{

		public:

			std_window();
			void show(int argc, char** argv);

		private:

			Fl_Window* window;
			Fl_Box* box;
			Fl_Return_Button* rbutton;
			Fl_Button* exitbutton;

			//static functions

			 Fl_Input* inputuser;
			 Fl_Output* output;

			static void cb_value(Fl_Widget* w, void* data);
			static void cb_exit(Fl_Widget* w);
			static void cb_output(Fl_Widget* w, void* data);
	}

fltk.cpp

#include "fltk.h"
	#include <string>
	#include <iostream>
	using namespace std;

	 std_window::std_window() {

		window = new Fl_Window(500, 650);

		window->begin();							//window begin

		box = new Fl_Box(50, 40, 400, 500, NULL);

		rbutton = new Fl_Return_Button(60,500,100,50);

		exitbutton = new Fl_Button(300, 500, 100, 50,"EXIT");

		box->box(FL_UP_BOX);
		box->labelsize(15);
		box->labelfont(FL_BOLD+FL_ITALIC);
		box->labeltype(FL_SHADOW_LABEL);

		window->end();						//window end

		inputuser->callback(cb_value,(void*)this );
		rbutton->callback(cb_output, (void*)this);
		exitbutton->callback(cb_exit);

	}

	void std_window::cb_value(Fl_Widget* w, void* data) {
		string temp;

		Fl_Input* input =((std_window*)data)->inputuser;
		temp = input->value();
		cout<<temp;

	}

	void std_window::cb_output(Fl_Widget*w, void* data) {
		Fl_Output* out = ((std_window*)data)->output;

		out->value("Daten wurden übernommen");

	}

	void std_window::cb_exit(Fl_Widget* w) {

		exit(1);
	}
