40 // SystemC 2.3
41 //
42 // Revision 1.2 2006/01/03 23:18:34 acg
43 // Changed copyright to include 2006.
44 //
45 // Revision 1.1.1.1 2005/12/19 23:16:43 acg
46 // First check in of SystemC 2.1 into its own archive.
47 //
48 // Revision 1.9 2005/09/15 23:02:03 acg
49 // Added std:: prefix to appropriate methods and types to get around
50 // issues with the Edison Front End.
51 //
52 // Revision 1.8 2005/06/07 17:27:02 acg
53 // Fixed bug in scfx_string::operator += where an array reference was used
54 // rather than the [] operator. This meant that the buffer may have been
55 // accessed beyond its allocated storage.
