 * $Log: main.h,v $
 * Revision 1.13  2001/08/03 09:01:02  robertj
 * Added assignement operator with RHS of PWORDArray to classes
 *   descended from PASN_BMPString.
 *
 * Revision 1.12  2001/06/14 02:09:20  robertj
 * Corrected support for ASN object class type reference constructs
 *   ie TYPE-IDENTIFIER.&Type encoded as octet string.
 *
 * Revision 1.11  2000/03/21 21:23:24  robertj
 * Added option to rename imported module names, allows include filename matching.
 *
 * Revision 1.10  1999/09/18 04:17:40  robertj
 * Added generation of C++ inlines for some  functions.
 * Optimised CreateObject() switch statements, collapsing common cases.
 *
 * Revision 1.9  1999/08/09 13:02:36  robertj
 * Added ASN compiler #defines for backward support of pre GCC 2.9 compilers.
 * Added ASN compiler #defines to reduce its memory footprint.
 * Added ASN compiler code generation of assignment operators for string classes.
 *
 * Revision 1.8  1999/07/22 06:48:56  robertj
 * Added comparison operation to base ASN classes and compiled ASN code.
 * Added support for ANY type in ASN parser.
 *
 * Revision 1.7  1999/06/30 08:57:20  robertj
 * Fixed bug in encodeing sequence of constrained primitive type. Constraint not set.
 * Fixed bug in not emitting namespace use clause.
 * Added "normalisation" of separate sequence of <base type> to be single class.
 *
 * Revision 1.6  1999/06/09 06:58:09  robertj
 * Adjusted heading comments.
 *
 * Revision 1.5  1999/06/07 01:56:26  robertj
