Bug 123543

Cumulative changes:

       * glplib.h, glplib.c
        Three wrapper routines xdlopen, xdlsym, and xdlclose, which
        provide the shared library support, were added. A particular
        version of these routines depends on the option --enable-dl
        passed to the configure script (see file INSTALL for details).
        Thanks to Rafael Laboissiere <rafael@debian.org> for useful
        advices concerning the shared library support.

        * glpsql.c
        A static linking to iODBC and MySQL libraries used in the
        MathProg table drivers was replaced by a dynamic linking to
        corresponding shared libraries.
        Many thanks to Heinrich Schuchardt <heinrich.schuchardt@gmx.de>
        for the contribution and to Vijay Patil <vijay.patil@gmail.com>
        for testing this feature under Windows XP.

        * glpgmp.h, glpgmp.c
        A bug (which appeared only on 64-bit platforms) was fixed.
        Thanks to Axel Simon <Axel.Simon@ens.fr> for the bug report.

        * glpapi.c
        A bug was fixed in the api routine glp_add_cols. (If the basis
        is valid, adding column keeps it valid, however, col->bind was
        set to -1 rather to 0.)
        Thanks to Cedric[FR] <fox2113@wanadoo.fr> for the bug report.

        * glplib.c
        64-bit unsigned int type glp_ulong and corresponding routines
        were replaced by 64-bit signed int type xlong_t.

        * glpk.h, glpapi.c
        The type glp_ulong was replaced by glp_long. This affects only
        the api routine glp_mem_usage.

        * glplib.c
        Compressed data file support was added. This feature requires
        the zlib data compression libraries and allows compressing and
        decompressing .gz files "on the fly".

        * glpcli.h, glpcli.c
        Command-line interface routines were added. (This feature is
        incomplete so far.)

        * glpsql.h, glpsql.c
        Two MathProg table drivers for iODBC and MySQL contributed by
        Heinrich Schuchardt <heinrich.schuchardt@gmx.de> were added to
        the package.

        * glpmpl05.c
        Mathprog table driver for xBASE was added to the package.

        * glpmpl03.c
        A minor was fixed in the MathProg translator (if some field
        specified in the table statement is missing in corresponding
        input table, the bug causes abnormal termination). Thanks to
        Heinrich Schuchardt <heinrich.schuchardt@gmx.de> for the bug
        report.

        * glpmpl.h, glpmpl.c
        STRING data type was replaced by plain character strings.

        * glpmpl.h, glpmpl01.c, glpmpl03.c, glpmpl05.c
        The table statement was implemented. Description of this new
        feature is given in file doc/tables.txt.

        * glpios03.c
        A bug causing zero divide error on computing euclidean norm of
        the cut coefficient vector was fixed.

Fix: Patch attached with submission follows:
