Where does ABC get defined if you compile your program normally?
It either needs to be defined in the sources e.g. some included header
or then it is given on the command line. In this case you need to adjust
the doxygen config and add ABC to the list of predefined macros. This
is the equivalent of -DABC for gcc.
