$Log$
Revision 1.10 2000-01-09 23:16:06 peter
* added st_default stringtype
* genstringconstnode extended with stringtype parameter using st_default
will do the old behaviour
Revision 1.9 2000/01/07 01:14:39 peter
* updated copyright to 2000
Revision 1.8 1999/12/18 14:55:21 florian
* very basic widestring support
Revision 1.7 1999/11/30 10:40:54 peter
+ ttype, tsymlist
Revision 1.6 1999/11/17 17:05:04 pierre
* Notes/hints changes
Revision 1.5 1999/11/07 23:16:49 florian
* finally bug 517 solved ...
Revision 1.4 1999/10/26 12:30:45 peter
* const parameter is now checked
* better and generic check if a node can be used for assigning
* export fixes
* procvar equal works now (it never had worked at least from 0.99.8)
* defcoll changed to linkedlist with pparaitem so it can easily be
walked both directions
Revision 1.3 1999/10/01 08:02:48 peter
* forward type declaration rewritten
Revision 1.2 1999/08/04 13:45:29 florian
+ floating point register variables !!
* pairegalloc is now generated for register variables
Revision 1.1 1999/08/03 22:03:14 peter
* moved bitmask constants to sets
* some other type/const renamings
