      Name, Affiliation, Date:  Jason Elbaum, Motorola, Inc., 2001-11-12
  Description of Modification:  Added a static, private, otherwise
                                unused data member to the sc_in
                                and sc_inout classes to address
                                a bug in the GNU compiler *only*.
                                This works around a bug in g++ 2.95.2
                                regarding implicit casting from a
                                templated class to a C++ intrinsic type.

//Revision 1.10  2011/08/29 18:04:32  acg
// Philipp A. Hartmann: miscellaneous clean ups.
//
//Revision 1.9  2011/08/26 20:45:43  acg
// Andy Goodrich: moved the modification log to the end of the file to
// eliminate source line number skew when check-ins are done.
//
//Revision 1.8  2011/08/07 19:08:01  acg
// Andy Goodrich: moved logs to end of file so line number synching works
// better between versions.
//
//Revision 1.7  2011/08/07 18:53:09  acg
// Philipp A. Hartmann: add virtual instances of the bind function for
// base classes to eliminate warning messages for clang platforms.
//
//Revision 1.6  2011/04/02 00:03:23  acg
// Andy Goodrich: catch the other bind()'s that I missed in Philipp's update.
//
//Revision 1.5  2011/04/01 22:33:31  acg
// Philipp A. Harmann: Use const interface signature to implement non-const
// interface signature for virtual bind(...).
//
//Revision 1.4  2011/03/30 16:46:10  acg
// Andy Goodrich: added a signature and removed a virtual specification
// to eliminate warnings with certain compilers.
//
//Revision 1.3  2011/02/18 20:23:45  acg
// Andy Goodrich: Copyright update.
//
//Revision 1.2  2011/01/20 16:52:15  acg
// Andy Goodrich: changes for IEEE 1666 2011.
//
//Revision 1.1.1.1  2006/12/15 20:20:04  acg
//SystemC 2.3
//
//Revision 1.11  2006/04/18 23:36:50  acg
// Andy Goodrich: made add_trace_internal public until I can figure out
// how to do a friend specification for sc_trace in an environment where
// there are partial template and full template specifications for its
// arguments.
//
//Revision 1.10  2006/04/18 18:01:26  acg
// Andy Goodrich: added an add_trace_internal() method to the various port
// classes so that sc_trace has something to call that won't emit an
// IEEE 1666 deprecation message.
//
//Revision 1.9  2006/03/13 20:19:44  acg
// Andy Goodrich: changed sc_event instances into pointers to sc_event instances
// that are allocated as needed. This saves considerable storage for large
// numbers of signals, etc.
//
//Revision 1.8  2006/02/02 23:42:37  acg
// Andy Goodrich: implemented a much better fix to the sc_event_finder
// proliferation problem. This new version allocates only a single event
// finder for each port for each type of event, e.g., pos(), neg(), and
// value_change(). The event finder persists as long as the port does,
// which is what the LRM dictates. Because only a single instance is
// allocated for each event type per port there is not a potential
// explosion of storage as was true in the 2.0.1/2.1 versions.
//
//Revision 1.7  2006/02/02 21:38:12  acg
// Andy Goodrich: fix to the comment log.
//
//Revision 1.4  2006/01/24 20:46:32  acg
//Andy Goodrich: changes to eliminate use of deprecated features. For instance,
//using notify(SC_ZERO_TIME) in place of notify_delayed().
//
//Revision 1.3  2006/01/13 18:47:42  acg
//Added $Log command so that CVS comments are reproduced in the source.
//
//Revision 1.2  2006/01/03 23:18:26  acg
//Changed copyright to include 2006.
//
//Revision 1.1.1.1  2005/12/19 23:16:43  acg
//First check in of SystemC 2.1 into its own archive.
//
//Revision 1.18  2005/09/15 23:01:52  acg
//Added std:: prefix to appropriate methods and types to get around
//issues with the Edison Front End.
//
//Revision 1.17  2005/06/10 22:43:55  acg
//Added CVS change log annotation.
