When you look at the gnulib/lib/dirent.in.h file, you see that it declares
only functions; it provides no types, enums, or macros. In such a situation,
it's sufficient for you to require the particular function modules (such as
'dirfd', 'scandir', etc.); the 'dirent' module will be pulled in implicitly,
as a dependency, if it is needed.

The documentation in [1] also mentions no particular reason for which you
would need to use the 'dirent' module. That may change over time, of course:
it is alwaus possible that we discover some portability problems and fix it
in the 'dirent' module.
