/** MicroSoft Visual C++ required macros, pragmas, and functions.  The
    macros are defined so alternate code can be conditionally compiled
    to work around the defects.  The pragmas are used to turn off some
    frequently seen warning messages.  The functions defined are part
    of the standard of the standard C++ library, but are missing from
    the MicroSoft library.

    This file is included directly when autoconf/automake is not being used
    on a MicroSoft Windows platform.  If autoconf/automake is being
    used, then it is also included in config.h.

    @todo @b Oded: Write a main program so that HippoDraw can be installed on
    the desktop. This reqires setting the path to the shared libraries
    correctly.

    @todo @b Oded: Associate icons with executable and document files.
    .bmp files for this purpose are in the images subdirectory.
