Add section for forward declarations of local functions. This section is
located before file scope variables because functions can be used in
strucutres (see find.c for example):
/*** forward declarations (file scope functions) *************************************************/
/* button callbacks */
static int start_stop (WButton * button, int action);
static int find_do_view_file (WButton * button, int action);
static int find_do_edit_file (WButton * button, int action);
/*** file scope variables ************************************************************************/
static struct
{
...
bcback_fn callback;
} fbuts[] =
{
...
{ B_STOP, NORMAL_BUTTON, N_("S&uspend"), 0, 0, NULL, start_stop },
...
{ B_VIEW, NORMAL_BUTTON, N_("&View - F3"), 0, 0, NULL, find_do_view_file },
{ B_VIEW, NORMAL_BUTTON, N_("&Edit - F4"), 0, 0, NULL, find_do_edit_file }
};
