    Simplify data_start configuration. · 1ddc2bd6
    Paul Eggert authored
    This is a followon simplification to the fix for Bug#13650.
    * admin/CPP-DEFINES (DATA_START, ORDINARY_LINK): Remove.
    * configure.ac (CRT_DIR, LIB_STANDARD, START_FILES, DATA_START)
    (LD_FIRSTFLAG, ORDINARY_LINK, LIB_GCC): Remove.
    (AC_CHECK_HEADERS_ONCE): Remove sys/resource.h, as it's
    not always needed.
    (HAVE_DATA_START): New macro.
    * etc/PROBLEMS (LIBS_SYSTEM, LIBS_MACHINE, LIBS_STANDARD): Remove.
    Remove legacy-systems section, as this stuff is no longer
    applicable with current linking strategies.
    * src/Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
    (START_FILES): Remove.  All uses removed.
    (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
    (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
    (buildobj.h): Use it.
    ($(ALLOBJS)): Depend on globals.h.
    (temacs$(EXEEXT)): Use $(ALLOBJS).
    * src/autodeps.mk (ALLOBJS): Move to Makefile.in.
    * src/deps.mk (vm-limit.o):
    * src/makefile.w32-in ($(BLD)/vm-limit.$(O)):
    Do not depend on mem-limits.h.
    * src/emacs.c (__do_global_ctors, __do_global_ctors_aux)
    (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
    [__GNUC__ && !ORDINARY_LINK]: Remove.
    * src/mem-limits.h, src/pre-crt0.c: Remove.
    * src/unexaix.c, src/unexcoff.c: Don't include mem-limits.h.
    * src/unexcoff.c (etext): New decl.
    (make_hdr): Use it instead of start_of_data.
    * src/vm-limit.c: Move most of mem-limits.h's contents here.
    (data_start): New decl.  It's OK if this is approximate,
    so simplify-away some unnecessary exactness.
    (POINTER): Remove; all uses removed.
    (data_space_start): Now char *, to avoid casts.
    (exceeds_lisp_ptr): New function, replacing the old
    EXCEEDS_LISP_PTR macro.  All uses changed.
    (check_memory_limits): Simplify and remove casts.
    (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
    (memory_warnings): Use data_start instead of start_of_data.
