This cannot be a compile-time condition, because Emacs compiled with X
support can still have TTY frames.  So you need to test for
FRAME_WINDOW_P, and only call x_y_to_hpos_vpos if FRAME_WINDOW_P
returns non-zero; otherwise call pixel_to_glyph_coords even in a build
where HAVE_WINDOW_SYSTEM is defined.
