The following patches are for when GLYPH_DEBUG && !XASSERT. * dispextern.h (trace_redisplay_p, dump_glyph_string): * dispnew.c (flush_stdout): * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph): Mark as externally visible. * dispnew.c (check_window_matrix_pointers): Now static. * dispnew.c (window_to_frame_vpos): * xfns.c (unwind_create_frame): * xterm.c (x_check_font): Remove unused local. * scroll.c (CHECK_BOUNDS): * xfaces.c (cache_fache): Rename local to avoid shadowing. * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static. * xdisp.c (check_window_end): Now a no-op if !XASSERTS. (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos) (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos): Now static. (debug_method_add): Use va_list and vsprintf rather than relying on undefined behavior with wrong number of arguments. (dump_glyph, dump_glyph_row, Fdump_glyph_matrix): Don't assume ptrdiff_t and EMACS_INT are the same width as int. In this code, it's OK to assume C99 behavior for ptrdiff_t formats since we're not interested in debugging glyphs with old libraries. * xfaces.c (cache_face): Move debugging code earlier; this pacifies GCC 4.6.0's static checking.
