        !            29: Wed May  4 18:32:46 1983 by layer

        !            35:        file (instead of the input file).
        !            36:        (now: version 8.25)
        !            37:        
        !            38: Sat Mar 19 17:49:18 1983 by jkf
        !            39:        mixed in the 68k liszt source.
        !            40:        (now: version 8.24)
        !            41:        
        !            42: Mon Mar 14 13:14:26 1983 by jkf
        !            43:        liszt used to open code 'times' if all operands were fixnums.
        !            44:        Thus (times 256 256 256 256) would open code to a 0 fixnum.
        !            45:        This is clearly wrong and liszt will now not convert times, add,
        !            46:        etc to their fixnum equivalents.  If you want fixnum semantics
        !            47:        then you must use fixnums.
        !            48:        Another bug was fixed: d-functyp would return the wrong thing
        !            49:        give a name bound to a foreign function.  now it returns 'lambda.
        !            50:        files affected: datab.l decl.l
        !            51:        (now: version 8.23)

        !            54:        force jump to vecindexerr to use 'jmp', since the object
        !            55:        file might be large and the assembler is stupid
        !            56:        (now: version 8.22)
        !            57:        
        !            58: Thu Feb 10 20:39:42 1983 by jkf
        !            59:        open coded vectorp and vectorip, vsize-...
        !            60:        (now: version 8.21)

        !            63:        Added three features to liszt command line processing:
        !            64:        -e <expr> evaluates <expr> before compilation.
        !            65:        -i <filename> loads <filename> before compilation.
        !            66:        -S -o filename names .s file.
        !            67:        file: tlev.l
        !            68:        (now: version 8.20)
        !            69:        
        !            70: Mon Jan 17 09:41:12 1983 by jkf
        !            71:        added arg number checking and open coded &keywords.

        !            75:        fixed nasty bug in d-exp which would show up if a macro
        !            76:        returned a recursive call it itself
        !            77:        (now: version 8.18)
        !            78:        
        !            79: Wed Jan 12 10:43:53 1983 by jkf
        !            80:        added open coding of vref functions
        !            81:        (now: version 8.17)
        !            82:        
        !            83: Wed Oct 27 20:24:47 1982 by jkf
        !            84:        removed references to sys_ functions, replaced them with
        !            85:        sys: functions so code will be more portable.
        !            86:        file: tlev.l
        !            87:        
        !            88: Wed Oct 27 08:15:14 1982 by jkf
        !            89:        discovered that making 'declare' a function is a bad idea because
        !            90:        if the compiler executes an interpreted function with local
        !            91:        declarations, those local declarations will seem like declarations
        !            92:        for the function begin compiled.   Thus declare is no longer a
        !            93:        special function in the compiler: it must be seen by the compiler
        !            94:        to have an effect.  Added the user callable function liszt-declare
        !            95:        which will have an effect just like declare used to: the compiler
        !            96:        will recognize it when compiling and it can be evaluated by a
        !            97:        user function.
        !            98:        (now: version 8.16)
        !            99:        
        !           100: Mon Oct 25 22:55:37 1982 by jkf
        !           101:        removed If macro definition from cmacros.l . It is now in
        !           102:        the default franz.
        !           103:        
        !           104: Mon Oct 25 09:15:18 1982 by jkf
        !           105:        catch the sigterm signal and die after removing the /tmp file.
        !           106:        (now: version 8.15)
        !           107:        
        !           108: Tue Oct 19 15:56:07 1982 by jkf
        !           109:        fixed bugin cc-arg wherein a (arg (foo)) would be compiled
        !           110:        incorrectly (it was calling zerop on a non number).
        !           111:        Added checks for cmacro and macro-autoload properties.
        !           112:        When doing macro expansion, had it stop if the same car
        !           113:        was returned.
        !           114:        (now: version 8.14)
        !           115:        
        !           116: Mon Oct 18 23:27:14 1982 by layer
        !           117:        Fixed bug in function cc-quote.  Parens in an If statement
        !           118:        were messed up.
        !           119:        
        !           120: Sat Oct  9 04:35:23 PDT 1982 by layer
        !           121:        Np-reg, Lbot-reg, oLbot-reg are now constants.  Changes
        !           122:        made to expr.l and io.l.
        !           123: 
        !           124: Thu Oct  7 01:02:26 1982 by jkf
        !           125:        fixed bug in the compiler.  The compiler had neglected to enforce
        !           126:        the rule that 'macros' not be defined as local functions.
        !           127:        Now that is checked (modification to tlev.l).
        !           128:        
        !           129: Wed Oct  6 22:53:36 1982 by jkf
        !           130:        added check to make sure that a file doesn't declare a function
        !           131:        to be local that has already had a compiled call made to it.
        !           132:        This is done by placing a t under indicator g-stdref for all
        !           133:        symbols called in the 'standard' way.
        !           134:        (now: version 8.13)
        !           135:        
        !           136: Wed Oct  6 13:29:27 PDT 1982 by layer
        !           137:        put the loading of chead.l (in array.l datab.l decl.l expr.l
        !           138:        fixnum.l funa.l funb.l func.l io.l tlev.l util.l) under
        !           139:        include-if control.  Also changed chead.l.
        !           140: 
        !           141: Tue Oct  5 23:36:09 PDT 1982 by layer
        !           142:        removed function d-call from expr.l, since it isn't
        !           143:        used anymore.
        !           144: 
        !           145: Tue Oct  5 23:00:09 PDT 1982 by layer
        !           146:        added sccs'ed file scmake.l, so that an all interp'd
        !           147:        version of the compiler can be made without deleting
        !           148:        all the .o files.  Changes were also make to the Makefile.
        !           149:        snliszt (formerly slownliszt) now depends on source
        !           150:        files (like nliszt depends on .o files).
        !           151: 
        !           152: Tue Oct  5 22:22:59 1982 by jkf
        !           153:        added argument checking.  This involved mods to expr.l to
        !           154:        do the checking and to tlev.l to save argument number
        !           155:        info while compiling.  The file /usr/lib/lisp/fcninfo.l
        !           156:        contains a description of what is known about C functions.
        !           157:        (now: version 8.12)
        !           158:        
        !           159: Mon Oct  4 14:23:29 1982 by jkf
        !           160:        turn off [load ...] message when loading in lisztrc file
        !           161:        
        !           162: Tue Sep 28 09:30:36 1982 by jkf
        !           163:        change tmp file name back to jkfnnnnn
        !           164:        (now: version 8.11)
        !           165:        
        !           166: Wed Jul 21 13:43:56 PDT 1982 by layer
        !           167:        function "liszt" in tlev.l now returns the true assembler exit
        !           168:        status (if the compile goes that far).
        !           169: 
        !           170: Sat Jul  3 18:01:25 1982 by jkf

        !           175:        look for liszt rc files without extensions.  now we look in 
        !           176:        12 places for the lisp init file:
        !           177:          { . , $HOME } { .lisztrc , lisztrc } { .o , .l , }
        !           178:        (now: version 8.09)
        !           179:        
        !           180: Thu May 27 08:19:00 1982 by jkf
        !           181:        fixed bug in d-fixnump which caused liszt to assume too often that
        !           182:        arguments are all fixnums
        !           183:        (now: version 8.08)
        !           184:        
        !           185: Wed May 12 13:46:03 1982 by jkf
        !           186:        new declaration scheme died when the object being declared
        !           187:        was a list. e.g (declare (fixnum (foo fixnum flonum)).
        !           188:        Fixed declare-handler so that cases like this are ignored.
        !           189:        (now: version 8.07)
        !           190: 
        !           191: Fri May  7 19:28:04 1982 by jkf
        !           192:        allow (function (nlambda ()...)) and (function (lambda () ..))

        !           196:        support local declarations.  They are stacked on g-decls.
        !           197:        localf and macarray don't fit in too well, they should
        !           198:        be fixed.  
        !           199:        fixnum declarations now have meaning.  They will allow the
        !           200:        compiler to convert from functions like 'add1' to 1+.
        !           201:        'declare' is now a function in the compiler so declarations

        !           247:        both bugs have to do with returning or going through a

        !           249:        The fix was to keep track of the number of catches and errsets

        !           251:        I modified d-pushframe to always push 3 args, so we can know

        !           256:        Added three internal functions fixnum-BitXor, fixnum-BitAndNot
        !           257:        fixnum-BitOr, which are the three functions which the vax

        !           278:        is a string saying what file this came from and when it was

        !           288:        amounts to checking that one of the operands is a fixnum.
        !           289:        We should augment to this check also for type declarations.

        !           292:        since most fixnums are in the range 0 to 1023 we can probably
        !           293:        win by doing inline checking in that range.  Thus I've added
        !           294:        the function d-fixnumbox which does an inline reboxing if
        !           295:        the number is between 0 and 1023 and otherwise calls qnewint.

        !           301:        (eq (cdr ..) (cdr ..)) which should do the trick.
