// $Log: lex.yy.cc,v $
// Revision 1.10.2.11  2004/10/17 20:14:34  dgrisby
// Updated support for OpenVMS. Many thanks to Bruce Visscher.
//
// Revision 1.9.2.8  2001/10/22 10:48:22  dpg1
// Cope with DOS line endings in all IDL situations.
//
// Revision 1.9.2.7  2001/10/17 16:48:32  dpg1
// Minor error message tweaks
//
// Revision 1.9.2.6  2001/06/13 11:28:20  dpg1
// Proper omniidl support for wchar/wstring constants.
//
// Revision 1.9.2.5  2001/03/13 10:32:10  dpg1
// Fixed point support.
//
// Revision 1.9.2.4  2000/11/01 12:45:55  dpg1
// Update to CORBA 2.4 specification.
//
// Revision 1.9.2.3  2000/10/27 16:31:07  dpg1
// Clean up of omniidl dependencies and types, from omni3_develop.
//
// Revision 1.9.2.2  2000/10/10 10:18:50  dpg1
// Update omniidl front-end from omni3_develop.
//
// Revision 1.7.2.8  2000/08/07 15:34:35  dpg1
// Partial back-port of long long from omni3_1_develop.
//
// Revision 1.7.2.7  2000/06/09 11:20:47  dpg1
// Last fix put __omni_pragma line numbers off by one...
//
// Revision 1.7.2.6  2000/06/08 14:58:19  dpg1
// Line numbers for #pragmas and // comments were off by one
//
// Revision 1.7.2.5  2000/06/08 14:36:19  dpg1
// Comments and pragmas are now objects rather than plain strings, so
// they can have file,line associated with them.
//
// Revision 1.7.2.4  2000/06/05 18:12:25  dpg1
// Support for __omni_pragma
//
// Revision 1.7.2.3  2000/04/26 09:55:48  dpg1
// cccp escapes characters like \ in line directives, so
// parseLineDirective() needs to use escapedStringToString().
//
// Revision 1.7.2.2  2000/03/06 15:03:49  dpg1
// Minor bug fixes to omniidl. New -nf and -k flags.
//
// Revision 1.7.2.1  2000/02/16 16:30:54  dpg1
// #pragma ID was misspelled #pragma id. Oops.
//
// Revision 1.7  2000/02/04 12:17:10  dpg1
// Support for VMS.
//
// Revision 1.6  1999/12/28 17:44:01  dpg1
// Stupid string allocation bug.
//
// Revision 1.5  1999/11/19 16:03:40  dpg1
// Flex scanner now accepts \r as whitespace.
//
// Revision 1.4  1999/11/05 10:36:42  dpg1
// Sorted out isatty() problems.
//
// Revision 1.3  1999/11/02 17:07:28  dpg1
// Changes to compile on Solaris.
//
// Revision 1.2  1999/11/01 10:05:00  dpg1
