See discussion in bug#5655.
* configure.in (machine, canonical): On amdx86-64, check for a 32-bit
userland and maybe change values to i386 (move test from s/amdx86-64.h).
* src/m/amdx86-64.h [i386]: Move this test to configure.in.
* emacs-lisp/easy-mmode.el (define-globalized-minor-mode):
Avoid re-enabling a minor mode after the user turned the minor mode
off if MODE-enable-in-buffers is run twice (typically once from
fundamental-mode's after-change-major-mode-hook and a second time from
run-mode-hook's own after-change-major-mode-hook).
* configure.in (LIBXTR6): New output variable. Move unixware special
case here from src/s/unixware.h.
* src/Makefile.in (LIBXTR6): Set with configure, not cpp.
* src/s/unixware.h (NEED_LIBW): Remove definition.
* admin/CPP-DEFINES: Remove NEED_LIBW.
* configure.in (LUCID_LIBW, MOTIF_LIBW): No longer substitute in Makefiles.
(TOOLKIT_LIBW): New output variable, replacing LUCID_LIBW/MOTIF_LIBW.
* src/Makefile.in (LUCID_LIBW, MOTIF_LIBW): Remove, replacing by...
(TOOLKIT_LIBW): New, set by configure.
(@X_TOOLKIT_TYPE@): No longer define it.
* configure.in (HAVE_MOTIF_2_1): Remove unused variable.
(LIBXP): No longer substitute in Makefiles.
(MOTIF_LIBW): New output variable. Move system-specific settings here
from src/s files.
* src/Makefile.in (LIBXP): Remove, since included in MOTIF_LIBW.
(MOTIF_LIBW): Set with configure, not cpp.
* s/aix4-2.h (LIB_MOTIF):
* s/gnu-linux.h (LIB_MOTIF):
* s/unixware.h (LIB_MOTIF): Move to configure.in.
* admin/CPP-DEFINES: Remove LIB_MOTIF.
* Makefile.in (C_SWITCH_SYSTEM, C_SWITCH_MACHINE, C_SWITCH_X_SITE): Remove
definitions and undefs. Inline definitions in the only user.
(ALL_CFLAGS): Substitute C_SWITCH_X_SYSTEM using autoconf.
* Makefile.in (C_SWITCH_X_SYSTEM): Define using autoconf.
* Makefile.in (C_SWITCH_X_SYSTEM): Define using autoconf.
* configure.in (C_SWITCH_X_SYSTEM): Define using autoconf, not cpp.
* Makefile.in (LIB_X11_LIB): Remove, inline in the only user.
(obj): Use autoconf for unexec instead of cpp.
* configure.in (LIB_X11_LIB): Remove, inline in the only user.
(unexec): Define unconditionally, all platforms define
UNEXEC. AC_SUBST it.
(UNEXEC_SRC): Remove, unused.
* configure.in (--with-crt-dir): Doc fix (now valid for all platforms).
(CRT_DIR): On (powerpc64|sparc64)-*-linux-gnu*, default to /usr/lib64.
On hpux10-20, default to /lib.
* src/m/amdx86-64.h (START_FILES, LIB_STANDARD): Change the logic around,
since the defaults (set by the system file) are fine in most cases.
[GNU_LINUX, __OpenBSD__, __NetBSD__, __APPLE__]: Remove sections.
* src/m/ibms390x.h (START_FILES, LIB_STANDARD):
* src/m/macppc.h (START_FILES, LIB_STANDARD) [GNU_LINUX]:
* src/m/sparc.h (START_FILES, LIB_STANDARD) [__linux__]:
Remove definitions, since they are set correctly in s/gnu-linux.h.
* src/s/freebsd.h (START_FILES, LIB_STANDARD):
* src/s/gnu-linux.h (START_FILES, LIB_STANDARD):
* src/s/hpux10-20.h (START_FILES):
* src/s/netbsd.h (START_FILES, LIB_STANDARD, START_FILES_1, END_FILES_1):
Use $CRT_DIR in place of fixed /usr/lib, /lib directories.
* src/Makefile.in: Comment.
* 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 (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)
