Just taking the first warning as an example: this has nothing to do with mc, this is a glib-2 upstream issue. In e.g. glib-2.68.3 we have these decls: glib/garray.h: void g_ptr_array_foreach(GPtrArray *array, GFunc func, gpointer user_data); The 'GFunc func' is the function pointer being cast. Also: glib/gtypes.h: typedef void (*GFunc) (gpointer data, gpointer user_data); and glib/gmem.h: void g_free (gpointer mem); The only way around these conflicting types (that I see) is an (inlined) wrapper function around g_free. Actually, I'd just use '-Wno-cast-function-type' or omit the '-Wextra'.
