The macro from legacy_macros.m4 turned out to be not legacy at all, but it is in fact needed a lot.

Hence, in the long term this test probably should have to be done by your external application, and in gnucash this #ifdef check should be moved to an internal header file.

Derek and I already agreed on this. Why is a long-term goal? Because it's not important for *gnucash*, hence it isn't a short-term goal *for gnucash*. Is it represent too much work? Yes. Unless you send in a patch - feel free to do so. When will GC clean up this issues to make easy other applications to use its data, may be to 2.4 or 3.0? No idea.

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.
