Making clang produce only pre-compiled output (with -E -dD) I cannot see a declaration. For use with GTK there seems to exist one in src/gtkutil.h, line #153:

	extern void x_wm_set_size_hint (FRAME_PTR f,
	                                long flags,
	                                int user_position);
