<<DEBUG MACROS>>
The code contains calls to 'debug_push' and 'debug_pop' macro.Theses
macro must be defined if you want to compile
the code, as a DLL or directly with yours.You can use the macros
defined in the demo program, they just do nothing
and your code will be unaffected.
Theses macros can be usefull with a debug stack to trace calls and
arguments with EXCEPT_Push(STRING) and
EXCEPT_Pop() calls.
