Indeed, it should not be removed.  Although we might want to move it into
a more "internal" header instead of exposing it in the "qof" interface.
But that's a discussion for a different day.

Copy the code from our configure.in into your configure.in.

Keep in mind that there IS no "GNCBook".  GNCBook was migrated to QofBook.
All the functions are qof_book_*.  The old "gnc_book" functions are
deprecated wrappers.

The old documentation you found is, well, old.. And wrong.  It was
probably written before I started working on GnuCash in 1999, and
it certainly has not been kept up to date since at LEAST GnuCash 1.4.
Right now the current developer docs are available at:
