* configure.in (LUCID_LIBW, LIBXP, WIDGET_OBJ): New output variables.
* src/Makefile.in (LIBXP, LUCID_LIBW, WIDGET_OBJ): Set via configure.
(MOTIF_LIBW): Use $LIBXP.
(otherobj): Use $WIDGET_OBJ.
* s/darwin.h (LIB_MATH): Do not define here, move to configure.
* s/cygwin.h (LIB_MATH): Likewise.
* Makefile.in (LIB_MATH): Do not define with cpp.
(LIBES): Use autoconf for LIB_MATH.
* configure.in (LIB_MATH): New output variable. Set it for some systems.
xdisp.c (set_cursor_from_row): Don't return zero if cursor was
found by `cursor' property of a display string.
(display_line): Preserve overlay and string info in row->end.
xdisp.c (display_line): Don't assume 2nd call to
get_next_display_element cannot return zero. (Bug#6030)
Move code that bidi-iterates out of display property to a separate function.
xdisp.c (iterate_out_of_display_property): New function, body from pop_it.
(pop_it): Use it.
* m/amdx86-64.h (START_FILES, LIB_STANDARD) [__OpenBSD__]:
For clarity, revert to using fixed /usr/lib rather than $CRT_DIR.
(START_FILES, LIB_STANDARD) [__FreeBSD__]: Merge into the generic case,
since CRT_DIR defaults to /usr/lib. Suggested by Dan Nicolaescu.
xdisp.c (display_line): Use `reseat' instead of `reseat_1', and
use `get_next_display_element' and `set_iterator_to_next' to
advance to the next character, when looking for the character that
begins the next row.
xdisp.c (display_line): Use `reseat' instead of `reseat_1', and
use `get_next_display_element' and `set_iterator_to_next' to
advance to the next character, when looking for the character that
begins the next row.
* configure.in (CRT_DIR): New output variable.
(--with-crt-dir): New option. (Bug#5655)
(HAVE_LIB64_DIR): Remove.
* src/Makefile.in (CRT_DIR): New variable, set by configure.
* src/m/amdx86-64.h, m/ibms390x.h (START_FILES, LIB_STANDARD):
Use $CRT_DIR rather than HAVE_LIB64_DIR. (Bug#5655)
* m/intel386.h (CRT0_DUMMIES): Remove, inline value in the only
user: ecrt0.c.
(SOLARIS2): Remove LOAD_AVE_TYPE, LOAD_AVE_CVT, LIBS_MACHINE, unused.
(USG5_4): Move LOAD_AVE_TYPE, LOAD_AVE_CVT, FSCALE definitions to
the only user: s/unixware.h.
* ecrt0.c: Remove #ifndef static. Inline CRT0_DUMMIES definition
from m/intel386.h.
* s/unixware.h (LOAD_AVE_TYPE, LOAD_AVE_CVT, FSCALE): Definitions
moved here from m/intel386.h.
xdisp.c (set_iterator_to_next, next_element_from_composition): After
advancing IT past the composition, resync the bidi iterator with
IT's position. (Bug#5977)
* emacs-lisp/bytecomp.el (byte-compile-set-default): New function.
(byte-compile-setq-default): Optimize for the
single-var case and don't call byte-compile-form in this case to avoid
inf-loop with byte-compile-set-default.
xdisp.c (pop_it): When the stack is popped after displaying
from a string, bidi-iterate to exit from the text portion covered
by the `display' property or overlay. (Bug#5988, bug#5920)
xdisp.c (pop_it): When the stack is popped after displaying
from a string, bidi-iterate to exit from the text portion covered
by the `display' property or overlay. (Bug#5988, bug#5920)
* s/hpux10-20.h (START_FILES): Explicitly define here instead of
relying on Makefile.in to define it.
* s/cygwin.h (START_FILES): Likewise.
* Makefile.in (STARTFILES): Remove conditional code, not needed anymore.
