Right.  What about "common" macros, such as ones that involve type
names?

For example, here is some sample GLib code, and GLib is a library used
widely throughout GNOME and freedesktop.org:

#ifdef HAVE_GTK3
static void emacs_menu_bar_get_preferred_width (GtkWidget *, gint *, gint *);
static GType emacs_menu_bar_get_type (void);

typedef struct _EmacsMenuBar
{
  GtkMenuBar parent;
} EmacsMenuBar;

typedef struct _EmacsMenuBarClass
{
  GtkMenuBarClass parent;
} EmacsMenuBarClass;

G_DEFINE_TYPE (EmacsMenuBar, emacs_menu_bar, GTK_TYPE_MENU_BAR)
#endif

Note how the the macro has no trailing semicolon.  That is required for
it to work correctly (I don't know why.)
