I would advise against that. Identifiers that begin with _GL are
Gnulib-private. That means, they can change their meaning or their
spelling, or go away entirely, at any moment. They are not part
of the formal interface of any module.

Instead, I would suggest to use a proper module with a defined
interface, namely the 'attribute' module. This module exports a
macro 'MAYBE_UNUSED', which is documented in attribute.h.
