        * Version 2.4 released.

        * marst.c
        Four serious bugs were fixed due to a test program provided by
        Jan van Katwijk <J.vanKatwijk@ITS.TUDelft.NL>. Because of these
        bugs references to wrong procedure DSAs were generated.

        The first three bugs appeared in a context like follows:

        ...
        procedure a(x);
        <specification of x>;
        begin
          ...
          procedure b(...);
          begin
            ...
            c(x);
            ...

        for which, in the cases when x was a simple formal parameter
        called by name, or a formal switch, or a formal procedure, the
        code was generated as if the parameter x were specified in the
        procedure b, not in a.

        To fix these bugs the context 'current_level()' was replaced by
        the correct context 'dsa_level(id)' in the lines 1738, 1826 and
        1917 within the routine 'actual_parameter'.

        The fourth bug appeared in a context like follows:

        ...
        <type> procedure a(...);
        begin
          ...
          procedure b(...);
          begin
            ...
            a := ...
            ...

        for which the code was generated as if assignment were made to
        the procedure identifier b, not to a.

        To fix this bug the context 'current_level()' was replaced by
        the correct context 'dsa_level(id)+1' in the line 3158 within
        the routine 'assignment_statement'.

        * alglib1.alg
        All standard functions and procedures written in Algol 60 were
        merged into one file.

        * alglib2.c, alglib3.c
        Other two files containing run-time routines written in C were
        renamed.

        * Version 2.3 released.

        The copyright notice was changed, because the copyright was
        transferred to the Free Software Foundation, Inc.

Mon Jan 22 12:00:00 2001 Andrew Makhorin <mao@mai2.rcnet.ru>

        * Version 2.2 released.

        * marst.c
        Serious bug was fixed due to bug report provided by Paulo
        Barreto <paulo.barreto@terra.com.br>.

        The error occurred because of incorrect passing a formal
        parameter called by name to other procedure. The MARST
        translator *incorrectly* treated a procedure statement like
        foo(..., bar, ...), where `bar' is a formal parameter called
        by name, as if it would be foo(..., (bar), ...), i.e. as if
        the value of `bar' would be passed, not the name. Therefore
        assignment to the corresponding formal parameter inside the
        procedure `foo' was impossible. In order to fix this bug a
        program fragment was added to the `actual_parameter' routine.

        * ex/a232.alg, ex/tennent.alg
        These two additional examples were added to the package. Due
        to the first example program a serious bug (see notice above)
        was found in MARST 2.1.

Fri Dec 01 12:00:00 2000 Andrew Makhorin <mao@mai2.rcnet.ru>

        * Version 2.1 released.

        * macvt.c
        Minor bug was fixed due to bug report provided by Bernhard
        Treutwein <Bernhard.Treutwein@Verwaltung.Uni-Muenchen.DE>
        (because of this bug the macvt converter incorrectly processed
        --ignore-case command line option)

        GNU MARST User's Guide is included into the distribution in
        texinfo (source), info, ps, pdf, and html formats.

Tue Aug 01 12:00:00 2000 Andrew Makhorin <mao@mai2.rcnet.ru>

        * Version 2.0 released.

        * marst.c
        Parsing implemented in the translator was fully re-programmed
        to continue translation in spite of syntax and semantic errors.
        In version 1.0 the translator had got an inborn defect (not a
        bug): it stopped on the first error found.

        * macvt.c
        Minor changes were made.

        * configure.in, Makefile.in
        Minor changes were made due to patches provided by Alexandre
        Oliva <oliva@lsd.ic.unicamp.br>.

Tue Jul 18 12:00:00 2000 Andrew Makhorin <mao@mai2.rcnet.ru>

        * Version 1.0 released under GNU Coding Standards.
