Hi,

if a class property last is defined the c compilation fails for classes derived from GLIB.Object
used vala version: Vala 0.38.2

public class Foo : Object {
    public string last { get; set; }
    public static int main(string[] args) {
        return 0;
    }
}

$ valac foo.vala 
foo.vala.c:24:2: Fehler: Redeklaration von Aufzählung »FOO_LAST_PROPERTY«
  FOO_LAST_PROPERTY
  ^~~~~~~~~~~~~~~~~
foo.vala.c:23:2: Anmerkung: Vorherige Definition von »FOO_LAST_PROPERTY« war hier
  FOO_LAST_PROPERTY,
  ^~~~~~~~~~~~~~~~~
error: cc exited with status 256


the part in the created c file:
typedef struct _FooPrivate FooPrivate;
enum  {
	FOO_DUMMY_PROPERTY,
	FOO_LAST_PROPERTY,
	FOO_LAST_PROPERTY
};
