12 - fixes for MinGW build
13
14V27 - 11/22/2010
15 - Fixed REPOSITION-FILE FILE-SIZE and FILE-POSITION.
16 They used to use single precision offset. Now use double as specified.
17 - Delete object directories in Makefile clean.
18 - Fixed "Issue 4: Filehandle remains locked upon INCLUDE error".
19 http://code.google.com/p/pforth/issues/detail?id=4&can=1
20 - Fixed scrambled HISTORY on 64-bit systems. Was using CELL+ but really needed 4 +.
21 - Fixed floating point input. Now accepts "1E" as 1.0. Was Issue #2.
22 - Fixed lots of warning and made code compatible with C89 and ANSI. Uses -pedantic.
23 - Use fseek and ftell on WIN32 instead of fseeko and ftello.
24 - Makefile is now more standard. Builds in same dir as Makefile. Uses CFLAGS etc.
25 - Add support for console IO with _WATCOMC_
26 - Internal CStringToForth and ForthStringToC now take a destination size for safety.
27 - Run units tests for CStringToForth and ForthStringToC if PF_UNIT_TESTS is defined.
28
29V26 5/20/2010
30 - 64-bit support for M* UM/MOD etc by Aleksej Saushev. Thanks Aleksej!
31
32V25 5/19/2010
33 - Added 64-bit CELL support contributed by Aleksej Saushev. Thanks Aleksej!
34 - Added "-x c" to Makefile CCOPTS to prevent confusion with C++
35 - Allow space after -d command line option.
36 - Restore normal tty mode if pForth dictionary loading fails.
37
38V24 2/20/09
39 - Fixed Posix IO on Mac. ?TERMINAL was always returning true.
40 - ACCCEPT now emits a space at end of line before output.
41 - Fixed RESIZE because it was returning the wrong address.
42
43V23 8/4/2008
44 - Removed -v option from mkdir in build/unix/Makefile. It was not supported on FreeBSD.
45 Thank you Alexsej Saushev for reporting this.
46
47V23 7/20/2008
48 - Reorganized for Google Code project.
49
50V22 (unreleased)
51 - Added command line history and cursor control words.
52 - Sped up UM* and M* by a factor of 3. Thanks to Steve Green for suggested algorithm.
53 - Modified ACCEPT so that a line at the end of a file that does NOT have a line
54 terminator will now be processed.
55 - Use _getch(), _putch(), and _kbhit() so that KEY, EMIT and ?TERMINAL will work on PC.
56 - Fixed : foo { -- } 55 ; - Was entering local frame but not exiting. Now prints error.
57 - Redefined MAKE_ID to protect it from 16 bit ints
58 - John Providenza says "If you split local variables onto 2 lines, PForth crashes." Fixed. Also allow \
59 - Fixed float evaluation in EVALUATE in "quit.fth".
60 - Flush register cache for ffColon and ffSemiColon to prevent stack warnings from ;
61
62V21 - 9/16/1998
63 - Fixed some compiler warnings.
64
65V20
66 - Expand PAD for ConvertNumberToText so "-1 binary .s" doesn't crash.
67 Thank you Michael Connor of Vancouver for reporting this bug.
68
69 - Removed FDROP in REPRESENT to fix stack underflow after "0.0 F.".
70 Thank you Jim Rosenow of Minnesota for reporting this bug.
71 - Changed pfCharToLower to function to prevent macro expansion bugs under VXWORKS
72 Thank you Jim Rosenow of Minnesota for reporting this bug.
73
74 - "0.0 F~" now checks actual binary encoding of floats. Before this it used to just
75 compare value which was incorrect. Now "0.0 -0.0 0.0 F~" returns FALSE.
76
77 - Fixed definition of INPUT$ in tutorial.
78 Thank you Hampton Miller of California for reporting this bug.
79
80 - Added support for producing a target dictionary with a different
81 Endian-ness than the host CPU. See PF_BIG_ENDIAN_DIC and PF_LITTLE_ENDIAN_DIC.
82
83 - PForth kernel now comes up in a mode that uses BASE for numeric input when
84 started with "-i" option. It used to always consider numeric input as HEX.
85 Initial BASE is decimal.
86
87V19 4/1998
88
89 - Warn if local var name matches dictionary, : foo { count -- } ;
90 - TO -> and +-> now parse input stream. No longer use to-flag.
91 - TO -> and +-> now give error if used with non-immediate word.
92 - Added (FLITERAL) support to SEE.
93 - Aded TRACE facility for single step debugging of Forth words.
94 - Added stub for ?TERMINAL and KEY? for embedded systems.
95 - Added PF_NO_GLOBAL_INIT for no reliance on global initialization.
96 - Added PF_USER_FLOAT for customization of FP support.
97 - Added floating point to string conversion words (F.) (FS.) (FE.)
98 For example: : F. (F.) TYPE SPACE ;
99 - Reversed order that values are placed on return stack in 2>R
100 so that it matches ANS standard. 2>R is now same as SWAP >R >R
101 Thank you Leo Wong for reporting this bug.
102
103 - Added PF_USER_INIT and PF_USER_TERM for user definable init and term calls.
104
105 - FIXED memory leak in pfDoForth()
106
107V18
108 - Make FILL a 'C' primitive.
109 - optimized locals with (1_LOCAL@)
110 - optimized inner interpreter by 15%
111 - fix tester.fth failures
112 - Added define for PF_KEY_ECHOS which turns off echo in ACCEPT if defined.

114 - Fixed saving and restoring of TIB when nesting include files.
115
116V17

121 'C' glue routines. This will ifndef the published example.
122 - Fixed warning in pf_cglue.c.
123 - Fixed SDAD in savedicd.fth. It used to generate bogus 'C' code
124 if called when (BASE != 10), as in HEX mode.
125 - Fixed address comparisons in forget.fth and private.fth for
126 addresses above 0x80000000. Must be unsigned.
127 - Call FREEZE at end of system.fth to initialize rfence.
128 - Fixed 0.0 F. which used to leave 0.0 on FP stack.
129 - Added FPICK ( n -- ) ( i*f -- i*f f[n] )
130 - .S now prints hex numbers as unsigned.
131 - Fixed internal number to text conversion for unsigned nums.
132
133V15 - 2/15/97
134 * If you use PF_USER_FILEIO, you must now define PF_STDIN and PF_STDOUT
135 among other additions. See "pf_io.h".
136 * COMPARE now matches ANS STRING word set!
137 - Added PF_USER_INC1 and PF_USER_INC2 for optional includes
138 and host customization. See "pf_all.h".
139 - Fixed more warnings.
140 - Fixed >NAME and WORDS for systems with high "negative" addresses.
141 - Added WORDS.LIKE utility. Enter: WORDS.LIKE EMIT
142 - Added stack check after every word in high level interpreter.
143 Enter QUIT to enter high level interpreter which uses this feature.
144 - THROW will no longer crash if not using high level interpreter.
145 - Isolated all host dependencies into "pf_unix.h", "pf_win32.h",
146 "pf_mac.h", etc. See "pf_all.h".
147 - Added tests for CORE EXT, STRINGS words sets.
148 - Added SEARCH
149 - Fixed WHILE and REPEAT for multiple WHILEs.
150 - Fixed .( ) for empty strings.
151 - Fixed FATAN2 which could not compile on some systems (Linux gcc).
152
153V14 - 12/23/96
154 * pforth command now requires -d before dictionary name.
155 Eg. pforth -dcustom.dic test.fth
156 * PF_USER_* now need to be defined as include file names.
157 * PF_USER_CHARIO now requires different functions to be defined.
158 See "csrc/pf_io.h".

160 file with main().
161 - Fix build with PF_NO_INIT
162 - Makefile now has target for embedded dictionary, "gmake pfemb".
163
164V13 - 12/15/96
165 - Add "extern 'C' {" to pf_mem.h for C++

167 dictionary but also have file I/O.
168 - Added PF_USER_FILEIO, PF_USER_CHARIO, PF_USER_CLIB.
169 - INCLUDE now aborts if file not found.
170 - Add +-> which allows you to add to a local variable, like +! .
171 - VALUE now works properly as a self fetching constant.
172 - Add CODE-SIZE and HEADERS-SIZE which lets you resize
173 dictionary saved using SAVE-FORTH.

175 - Fixed bug in local variables that caused problems if compilation
176 aborted in a word with local variables.
