Problems compiling my application on other computer

[hm <z_b_r poczta fm>]

Hi ! 

  Once again problem. I`m trying to compile my application on debian system. I`ve compiled it before on my own gentoo with kernel 2.6.x ( newest gcc and gtk ) and everything went ok. Now, on debian with kernel 2.4.x ( gcc 3.6.x and gtk+-2.0 ) i`m receiving following message : 

myhost# gcc rozkladGUI.c `pkg-config gtk+-2.0 --libs --cflags`

In file included from /usr/include/gtk-2.0/gtk/gtk.h:31,
                 from rozkladGUI.c:1:
/usr/include/gtk-2.0/gdk/gdk.h:70: error: parse error before '*' token
In file included from /usr/include/gtk-2.0/gtk/gtk.h:114,
                 from rozkladGUI.c:1:
/usr/include/gtk-2.0/gtk/gtkmain.h:101: error: parse error before "GOptionEntry"
/usr/include/gtk-2.0/gtk/gtkmain.h:105: error: parse error before '*' token
/usr/include/gtk-2.0/gtk/gtkmain.h:105: warning: data definition has no type or storage class

..what`s wrong ? :>
