source: code/branches/buildsystem/src/tinyxml/ticpprc.h @ 2138

Last change on this file since 2138 was 2138, checked in by rgrieder, 16 years ago

Added #define TIXML_USE_TICPP to the ticpp and tinyxml headers.
All the other changes (missing include, const, public & protected qualifiers, verbose errors) have been fixed by ticpp anyway.
