+ 27.12.2000 Goetz
+ Now outputs warning if faulty type in irdump, dump_type_info.
+ Explicit string termination in irdump, vcg_open.
+
+ 20.12.2000 Goetz
+ Added external to declaration of irp.
+ Added typedef before pns and pnc_number.
+ irmode.c, init_mode(): We need to memset all new modes as
+ tarval_vrfy reads fields before they are initialized: It
+ compares to min/max when tarvals for min/max are allocated!
+
+ 18.12.2000 Goetz
+ Changed parameter of Methods in type.h and type.c from
+ class to clss. Class is a C++ keyword.
+
+ 10.12.2000 Goetz
+ Changed some testprograms to accomodate Uebprakt.
+
+ 7.9.2000 Goetz
+ Finished implementation of dump_all_types.
+ Added new testprogram inheritance_example.
+
+ 6.9.2000 Chris
+ Added seven access routines in type.[hc]:
+ get_class_n_member, get_class_n_subtype, get_class_n_supertype,
+ get_strct_n_member, add_strct_member, get_strct_member and set_strct_member.
+ Fixed the type_walk_2 for those seven routines.
+
+ 6.9.2000 Goetz
+ Added irdump routine dump_all_types.
+ Did changes to irprog, type, typewalk to achieve this.
+ typewalk needs to walk along members, sub and supertypes, this
+ is still missing! irdump then needs to output these edges.
