Doxygen не отображает макросы в модуле

Написал следующий код:

/*****************************************************************//**

Но когда я создаю документацию с помощью doxygen, я вижу это: Хотя по идее в модуле должны быть ещё и макросы (В моём случае BMODULESNET_ARCH64 и BMODULESNET_ARCH 64). Если добавить определение макросов в начало, где объявляется модуль, то всё становится нормально:

Но в таком случае смысла от этих макросов 0. Как с этим бороться?
