        !          3013: 
        !          3014:        * alloc.c: New garbage collection technique for strings.
        !          3015: 
        !          3016:        Strings that have string blocks individually allocated
        !          3017:        are called "large strings".  Other strings are called "small".
        !          3018: 
        !          3019:        The string blocks for small strings are now chained both ways and
        !          3020:        there is a pointer to the oldest one of them in `first_string_block'.
        !          3021:        The string blocks for large strings are chained only from the
        !          3022:        latest to the oldest, and the latest is in `large_string_blocks'.
        !          3023: 
        !          3024:        Garbage collection starts by setting MARKBIT in the `size' of
        !          3025:        each large string.  This allows mark_object to distinguish them.
        !          3026:        MARKBIT in string sizes is cleared by gc_sweep.
        !          3027: 
        !          3028:        Large strings are freed individually by GC, like vectors.
        !          3029:        Those in use are marked with ARRAY_MARK_FLAG in the `size' field.
        !          3030: 
        !          3031:        Small strings are relocated, compressing them within their
        !          3032:        string blocks.  
        !          3033:        mark_object puts all slots that point at a string onto a chain
        !          3034:        which runs from the string's `size' field, through all the slots
        !          3035:        that used to point at the string.  The end of the chain is shown
        !          3036:        by a number that is small enough to be a small string's length.
        !          3037: 
        !          3038:        This new technique avoids calling malloc during GC.  Thus, there
        !          3039:        is no danger of fatal error on exhausting memory.  Also, space
        !          3040:        needed for strings is cut in half.
        !          3041: 
        !          3042:        The new technique introduces a potential for bugs, however.
        !          3043:        If any slot is marked twice--for example, if it is GCPRO'd
        !          3044:        twice by different functions--and it contains a string,
        !          3045:        the ref chain of the string may become garbled.  Sometimes
        !          3046:        it will still work!  This is because a slot that's part of a
        !          3047:        string's ref chain will look like a Lisp_Int if the next thing
        !          3048:        in the chain is malloc'd memory.  But this will not win if the
        !          3049:        next thing in the chain is a stack slot, or if malloc'd data
        !          3050:        lives high up in memory.
        !          3051: 
        !          3052:        To avoid this problem, MARKBIT is used in stack slots
        !          3053:        to prevent double marking.
        !          3054: 
        !          3055:        * bytecode.c (Fbytecode): Adjustment of gcpro1.nvars before
        !          3056:        call to Ffuncall was off by one.
        !          3057: 
        !          3058:        * alloc.c (make_uninit_string): make_zero_string renamed as this
        !          3059:        and no longer zeros the contents.
        !          3060:        * alloc.c (Fmake_string): initialize string contents.
        !          3061: 
        !          3062:        * alloc.c (struct string_block): Now chained both ways thru
        !          3063:        `next' and `prev' fields.  `first_string_block' exists.
        !          3064:        Strings with individual string blocks are now called "large"
        !          3065:        and these string blocks go in a separate chain which starts
        !          3066:        from `large_string_blocks' and runs via `prev' fields only.
        !          3067: 
        !          3068:        * alloc.c: Stop using clear_marks.  Make gc_sweep clear
        !          3069:        the marks on all live objects.
        !          3070:        
        !          3071:        * alloc.c (malloc_warning, Fgarbage_collect): Eliminate mechanism
        !          3072:        that defers malloc warnings during GC, since GC no longer calls
        !          3073:        malloc.
        !          3074: 
        !          3075:        * fns.c: Fding requires an arg; pass Qnil.
        !          3076: 
        !          3077:        * m-alliant.h: define TEXT_START as 0x1000.
        !          3078:        Don't define LIBS_STANDARD; the default (sharable) library

        !          5049:        Now Frecursive_edit calls command_loop, which does the catches
        !          5050:        and calls command_loop_2, which does the error handling,
        !          5051:        which calls command_loop to do the real work.
        !          5052:        Also, top_level_1 does a condition-case around top_level_2,
        !          5053:        which does the work.
        !          5054: 
        !          5055:        Previously, the error handling was outside the catch for
        !          5056:        top-level.  Then if handling an error ran an unwind protect form,
        !          5057:        the catch was not in effect; so ^G, or the debugger Q command,
        !          5058:        would not work inside of them.

        !          5065: 
        !          5066:        * keyboard.c (get_char):
        !          5067:        If rereading a char, do put it in the echo buffer
        !          5068:        if the echo buffer is empty.  Fixes problem that
        !          5069:        C-s C-h would never echo the C-h.
        !          5070: 
        !          5071:        * window.h: New window slot start_at_line_beg,
        !          5072:        holds t if window's start was the beginning of a line.
        !          5073:        * window.c: update this wherever ->start is updated.
        !          5074:        (But not always correctly).
        !          5075:        * xdisp.c (redisplay_window): update start_at_line_beg,
        !          5076:        and also find a new start if the old start used to be
        !          5077:        a line beginning but no longer is (which implies text

        !          5080:        * keyboard.c (get_input_pending):
        !          5081:        Don't bother with FIONREAD if interrupt_input;
        !          5082:        just use kbd_count.
        !          5083: 
        !          5084:        * fns.c: Assume KERNEL_FILE, LDAV_SYMBOL and NLIST_STRUCT
        !          5085:        are fully set up by the s- and m- files.
        !          5086: 
        !          5087:        * emacs.c (main): Don't call `signal' if in batch mode
        !          5088:        and not initialized and dumping is possible.
        !          5089:        * keyboard.c (init_keyboard): likewise for SIGIO.
        !          5090: 
        !          5091:        * unexec.c (make_hdr): Copy entire header of old file
        !          5092:        as base for header of new file.  Eliminates most
        !          5093:        machine-specific conditionals.

        !          5102: 
        !          5103:        * fileio.c (Ffile_exists_p):  this is now distinct from
        !          5104:        Ffile_readable_p; it checks only for existence, not for
        !          5105:        readability.
        !          5106: 
        !          5107:        * editfns.c (Fgoto_char): Use new interactive code N.

        !          5124:        conditionals in many places.  Use INTERRUPTABLE_OPEN
        !          5125:        and INTERRUPTABLE_IO conditionals to decide whether to
        !          5126:        include the functions sys_read, sys_write, sys_open.
        !          5127:        child_setup_tty must do FIOASYNC on masscomp.
