source: code/trunk/src/libraries/core/ToluaInterface.h @ 8666

Last change on this file since 8666 was 8418, checked in by rgrieder, 14 years ago

Added preprocessor macro UNIQUE_NUMBER which will return a new integer number every time is invoked if such a mechanism is available.
On GCC < 4.3, it will be defined as LINE. Newer GCC and MSVC support COUNTER, which is then used.
Also replaced uses of LINE with UNIQUE_NUMBER if appropriate.
