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?
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.
