(note_mouse_highlight, note_tool_bar_highlight): Set
help_echo_window.
(XTread_socket): Pass help_echo_window to gen_help_event.
(syms_of_xterm): Initialize and staticpro help_echo_window.
frame_or_window slot of TOOL_BAR_EVENT input events instead of
consing. For prefix events, store the frame in the `arg' slot of
the event, otherwise store the key there.
(XTread_socket): Instead of consing, use the frame_or_window slot
of HELP_EVENTs for the frame, and the `arg' slot for the help
string.
Obey open_paren_in_column_0_is_defun_start.
When reverting to the `slow' method, try to nicely handle the case
of nested comments by checking that the comment-starter we found
does indeed match the comment-ender.
(scan_sexps_forward, scan_sexps_forward):
Ignore excessive opening parenthesis rather than throwing an error.
* config.in (HAVE_SOUNDCARD_H): Undef.
(HAVE_SOUND): Define if HAVE_SOUNDCARD_H.
* Makefile.in (LIBSOUND): New variable.
(LIBES): Include it.
* sound.c [HAVE_SOUNDCARD_H]: Include <sys/ioctl.h> and <soundcard.h>.
(DEFAULT_SOUND_DEVICE): Define to "/dev/dsp" if not defined elsewhere.
(vox_open): Use DEFAULT_SOUND_DEVICE.
* s/netbsd.h (DEFAULT_SOUND_DEVICE): Define to /dev/audio.
(x_produce_image_glyph, x_append_stretch_glyph): Accomodate to
changes in struct glyph starting 1999-12-27. Some bit-fields of
struct glyph were not set, which made glyphs unequal when compared
with GLYPH_EQUAL_P. Redisplay outputs such glyphs, and flickering
effects were the result. This also depended on the contents of
memory returned by xmalloc. If flickering happens again, activate
the code in clear_glyph_row that's in #if 0. If the flickering is
gone with that, chances are that it is caused by something
similar.
