You can move the pragmas (and any ODB #include's that they require)
to a separate file or #ifdef them out using the ODB_COMPILER macro.
The introduction to Chapter 14, "ODB Pragma Language" has all the
details:

Of course that also means you persistent classes won't be able to
use some of the ODB feature that depend on types (and thus headers)
provided by ODB, such as lazy pointers, change-tracking contains,
and sections.
