Docstrings are now comments instead of C strings.
* build-aux/mk-opts.pl: Emit docstrings as comments instead of C
strings.
* DASPK-opts.in, LSODE-opts.in: Don't quote " in docstring fragments.
* builtins.h: Include builtin-defun-decls.h unconditionally.
* defun.h (DEFUN, DEFUNX, DEFCONSTFUN): Simply emit declaration.
(DEFALIAS): Always expand to nothing.
* defun-dld.h: No special macro expansions for MAKE_BUILTINS.
(DEFUN_DLD): Use FORWARD_DECLARE_FUN.
(DEFUNX_DLD): Use FORWARD_DECLARE_FUNX.
* defun-int.h: No special macro expansions for MAKE_BUILTINS.
(FORWARD_DECLARE_FUN, FORWARD_DECLARE_FUNX): New macros.
(DEFINE_FUN_INSTALLER_FUN): If compiling an Octave source file, pass
"external-doc" to DEFINE_FUNX_INSTALLER_FUN.
(DEFUN_INTERNAL, DEFCONSTFUN_INTERNAL, DEFUNX_INTERNAL,
DEFALIAS_INTERNAL): Delete.
* common.mk (move_if_change_rule): New macro.
(simple_move_if_change_rule): Define using move_if_change_rule.
* find-defun-files.sh (DEFUN_PATTERN): Update. Don't transform file
name extension to ".df".
* libinterp/mk-pkg-add, gendoc.pl: Operate directly on source files.
* mkbuiltins: New argument, SRCDIR. Operate directly on source files.
* mkdefs: Delete.
* libinterp/module.mk (BUILT_SOURCES): Update list to contain only
files included in other source files.
(GENERATED_MAKE_BUILTINS_INCS, DEF_FILES): Delete.
(LIBINTERP_BUILT_DISTFILES): Include $(OPT_HANDLERS) here.
(LIBINTERP_BUILT_NODISTFILES): Not here. Remove $(ALL_DEF_FILES from
the list.
(libinterp_EXTRA_DIST): Remove mkdefs from the list.
(FOUND_DEFUN_FILES): Rename from SRC_DEF_FILES.
(DLDFCN_DEFUN_FILES): Rename from DLDFCN_DEF_FILES.
(SRC_DEFUN_FILES): Rename from SRC_DEF_FILES.
(ALL_DEFUN_FILES): Rename from ALL_DEF_FILES.
(%.df: %.cc): Delete pattern rule.
(libinterp/build-env-features.cc, libinterp/builtins.cc,
libinterp/dldfcn/PKG_ADD): Use mv instead of move-if-change.
(libinterp/builtins.cc, libinterp/builtin-defun-decls.h):
Update mkbuiltins command.
($(srcdir)/libinterp/DOCSTRINGS): Update gendoc.pl command.
* liboctave/module.mk (BUILT_SOURCES): Don't include
liboctave-build-info.cc in the list.
