 {$ENDIF}
 
 I am about KYLIX.

the problem is the ...) construct in C; in FPC this used to be translated by 
array of const, but Kylix uses the varargs; modifier.

now, for FPC you should also use varargs, so the correct form is
 function gtk_list_store_new(n_columns:gint):PGtkListStore; varargs; cdecl; 
external gtklib;
both for FPC and Kylix.

 How can I use varargs if in fpc svn functions are declared with array of cont?

You cannot.

 
 Btw, returning to gtk2 package. Sources of that package are very old - they
 used only gtk 2.0 functions, structures and constants. 2.2, 2.4, 2.6, 2.8,
 2.10 and 2.12 versions were already released. Ofcource I understand that most
 of users still not using gtk 2.12, but at least gtk 2.4 can be taken as
 minimal requirement.

Feel free to update the sources. None of the FPC devels has time for this.
As far as I remember the GTK 2 sources were donated.

Michael.
