+        file_push checks array bounds (patch from Ray Lehtiniemi)
+        Changed to always use snprintf (Patch due to Ramiro bsd1628)
+        Updated usage information using text from the Manual.txt file.
+
+Version 1.38
+    Interim release until the rewrite, mostly incorporating modifications
+    from Kevin Cozens. Small addition for Cygwin in the makefile, and
+    modifications by Andrew Guenther for Apple platforms.
+
+Version 1.37
+    Joe Buehler submitted reserve_cells.
+
+Version 1.36
+    Joe Buehler fixed a patch in the allocator.
+    Alexander Shendi moved the comment handling in the scanner, which
+    fixed an obscure bug for which Mike E had provided a patch as well.
+    Kevin Cozens has submitted some fixes and modifications which have
+    not been incorporated yet in their entirety.
+
+Version 1.35
+    Todd Showalter discovered that the number of free cells reported
+    after GC was incorrect, which could also cause unnecessary allocations.
+
+Version 1.34
+    Long missing version. Lots of bugfixes have accumulated in my email, so
+    I had to start using them. In this version, Keenan Pepper has submitted
+    a bugfix for the string comparison library procedure, Wouter Boeke
+    modified some code that was casting to the wrong type and crashed on
+    some machines, "SheppardCo" submitted a replacement "modulo" code and
+    Scott Fenton submitted lots of corrections that shut up some compiler
+    warnings. Brian Maher submitted instructions on how to build on OS-X.
+    I have to dig deeper into my mailbox and find earlier emails, too.
+
+Version 1.33
+    Charles Hayden fixed a nasty GC bug of the new stack frame, while in
+    the process of porting TinyScheme to C++. He also submitted other
+    changes, and other people also had comments or requests, but the GC
+    bug was so important that this version is put through the door to
+    correct it.
+
+Version 1.32
+    Stephen Gildea put some quality time on TinyScheme again, and made
+    a whole lot of changes to the interpreter that made it noticeably
+    faster.
+
+Version 1.31
+    Patches to the hastily-done version 1.30. Stephen Gildea fixed
+    some things done wrongly, and Richard Russo fixed the makefile
+    for building on Windows. Property lists (heritage from MiniScheme)
+    are now optional and have dissappeared from the interface. They
+    should be considered as deprecated.
+
+Version 1.30
+    After many months, I followed Preston Bannister's advice of
+    using macros and a single source text to keep the enums and the
+    dispatch table in sync, and I used his contributed "opdefines.h".
+    Timothy Downs contributed a helpful function, "scheme_call".
+    Stephen Gildea contributed new versions of the makefile and
+    practically all other sources. He created a built-in STRING-APPEND,
+    and fixed a lot of other bugs.
+    Ruhi Bloodworth reported fixes necessary for OS X and a small
+    bug in dynload.c.
+
+Version 1.29
+    The previous version contained a lot of corrections, but there
+    were a lot more that still wait on a sheet of paper lost in a
+    carton someplace after my house move... Manuel Heras-Gilsanz
+    noticed this and resent his own contribution, which relies on
+    another bugfix that v.1.28 was missing: a problem with string
+    output, that this version fixes. I hope other people will take
+    the time to resend their contributions, if they didn't make it
+    to v.1.28.
+
+Version 1.28
+    Many people have contacted me with bugfixes or remarks in
+    the three months I was inactive. A lot of them spotted that
+    scheme_deinit crashed while reporting gc results. They suggested
+    that sc->outport be set to NIL in scheme_deinit, which I did.
+    Dennis Taylor remarked that OP_VALUEPRINT reset sc->value instead
+    of preserving it. He submitted a modification which I adopted
+    partially. David Hovemeyer sent me many little changes, that you
+    will find in version 1.28, and Partice Stoessel modified the
+    float reader to conform to R5RS.
+
+Version 1.27
+    Version 1.27 is the successor of 1.25. Bug fixes only, but I had to
+    release them so that everybody can profit. 'Backchar' tried to write
+    back to the string, which obviously didn't work for const strings.
+    'Substring' didn't check for crossed start and end indices. Defines
+    changed to restore the ability to compile under MSVC.
+
+Version 1.26
+    Version 1.26 was never released. I changed a lot of things, in fact
+    too much, even the garbage collector, and hell broke loose. I'll
+    try a more gradual approach next time.
+
+Version 1.25
+    Types have been homogenized to be able to accommodate a different
+    representation. Plus, promises are no longer closures. Unfortunately,
+    I discovered that continuations and force/delay do not pass the SCM
+    test (and never did)... However, on the bright side, what little
+    modifications I did had a large impact on the footprint:
+    USE_NO_FEATURES now produces an object file of 63960 bytes on Linux!
+
+Version 1.24
+    SCM tests now pass again after change in atom2str.
+
+Version 1.23
+    Finally I managed to mess it up with my version control. Version
+    1.22 actually lacked some of the things I have been fixing in the
+    meantime. This should be considered as a complete replacement for
+    1.22.
+
+Version 1.22
+    The new ports had a bug in LOAD. MK_CLOSURE is introduced.
+    Shawn Wagner inquired about string->number and number->string.
+    I added string->atom and atom->string and defined the number
+    functions from them. Doing that, I fixed WRITE applied to symbols
+    (it didn't quote them). Unfortunately, minimum build is now
+    slightly larger than 64k... I postpone action because Jason's idea
+    might solve it elegantly.
+
+Version 1.21
+    Jason Felice submitted a radically different datatype representation
+    which he had implemented. While discussing its pros and cons, it
+    became apparent that the current implementation of ports suffered
+    from a grave fault: ports were not garbage-collected. I changed the
+    ports to be heap-allocated, which enabled the use of string ports
+    for loading. Jason also fixed errors in the garbage collection of
+    vectors. USE_VERBATIM is gone. "ssp_compiler.c" has a better solution
+    on HTML generation. A bug involving backslash notation in strings
+    has been fixed. '-c' flag now executes next argument as a stream of
+    Scheme commands. Foreign functions are now also heap allocated,
+    and scheme_define is used to define everything.
+
+Version 1.20
+    Tracing has been added. The toplevel loop has been slightly
+    rearranged. Backquote reading for vector templates has been
+    sanitized. Symbol interning is now correct. Arithmetic functions
+    have been corrected. APPLY, MAP, FOR-EACH, numeric comparison
+    functions fixed. String reader/writer understands \xAA notation.
+
+Version 1.19
+    Carriage Return now delimits identifiers. DOS-formatted Scheme files
+    can be used by Unix. Random number generator added to library.
+    Fixed some glitches of the new type-checking scheme. Fixed erroneous
+    (append '() 'a) behavior. Will continue with r4rstest.scm to
+    fix errors.
+
+Version 1.18
+    The FFI has been extended. USE_VERBOSE_GC has gone. Anyone wanting
+    the same functionality can put (gcverbose #t) in init.scm.
+    print-width was removed, along with three corresponding op-codes.
+    Extended character constants with ASCII names were added.
+    mk_counted_string paves the way for full support of binary strings.
+    As much as possible of the type-checking chores were delegated
+    to the inner loop, thus reducing the code size to less than 4200 loc!
+
+Version 1.17
+    Dynamically-loaded extensions are more fully integrated.
+    TinyScheme is now distributed under the BSD open-source license.
+
+Version 1.16
+    Dynamically-loaded extensions introduced (USE_DL).
+    Santeri Paavolainen found a race condition: When a cons is executed,
+    and each of the two arguments is a constructing function,  GC could
+    happen before all arguments are evaluated and cons() is called, and
+    the evaluated arguments would all be reclaimed!
+    Fortunately, such a case was rare in the code, although it is
+    a pitfall in new code and code in foreign functions. Currently, only
+    one such case remains, when COLON_HOOK is defined.
+
+Version 1.15
+    David Gould also contributed some changes that speed up operation.
+    Kirk Zurell fixed HASPROP.
+    The Garbage Collection didn't collect all the garbage...fixed.
+
+Version 1.14
+    Unfortunately, after Andre fixed the GC it became obvious that the
+    algorithm was too slow... Fortunately, David Gould found a way to
+    speed it up.
+
+Version 1.13
+    Silly bug involving division by zero resolved by Roland Kaufman.
+    Macintoch support from Shmulik Regev.
+    Float parser bug fixed by Alexander Shendi.
+    GC bug from Andru Luvisi.
+
+Version 1.12
+    Cis* incorrectly called isalpha() instead of isascii()
+    Added USE_CHAR_CLASSIFIERS, USE_STRING_PORTS.
+
+Version 1.11
+    BSDI defines isnumber... changed all similar functions to is_*
+    EXPT now has correct definition. Added FLOOR,CEILING,TRUNCATE
+    and ROUND, courtesy of Bengt Kleberg. Preprocessor symbols now
+    have values 1 or 0, and can be set as compiler defines (proposed
+    by Andy Ganor *months* ago). 'prompt' and 'InitFile' can now be
+    defined during compilation, too.
+
+Version 1.10
+    Another bug when file ends with comment!
+    Added DEFINE-MACRO in init.scm, courtesy of Andy Gaynor.
+
+Version 1.09
+    Removed bug when READ met EOF. lcm.
+
+Version 1.08
+    quotient,remainder and modulo. gcd.
+
+Version 1.07
+    '=>' in cond now exists
+    list? now checks for circularity
+    some reader bugs removed
+    Reader is more consistent wrt vectors
+    Quote and Quasiquote work with vectors
+
+Version 1.06
+    #! is now skipped
+    generic-assoc bug removed
+    strings are now managed differently, hack.txt is removed
+    various delicate points fixed
+
+Version 1.05
+    Support for scripts, *args*, "-1" option.
+    Various R5RS procedures.
+    *sharp-hook*
+    Handles unmatched parentheses.
+    New architecture for procedures.
+
+Version 1.04
+    Added missing T_ATOM bits...
+    Added vectors
+    Free-list is sorted by address, since vectors need consecutive cells.
+    (quit <exitcode>) for use with scripts
+
+Version 1.03 (26 Aug 1998):
+    Extended .h with useful functions for FFI
+    Library: with-input-* etc.
+    Finished R5RS I/O, added string ports.
+
+Version 1.02 (25 Aug 1998):
+    First part of R5RS I/O.
