If there's a common header file shared by all the code, then probably
the simplest thing to do is to add this to the header file:

#ifdef __linux__
#include <endian.h>
/* Define betoh32, etc. */
#endif

using the functions in /usr/include/cdda/utils.h as a starting point.

Or if the OpenBSD functions are really macros, then even better would be:

#ifndef betoh32
#define ....
#endif

FWIW I've just ported a load of code which was written on Linux to
OpenBSD and Solaris, and I'm constantly surprised by how much Solaris
(in particular) and OpenBSD lack in their APIs. Really basic stuff
like Solaris not having 'setenv(3)'. I'm amazed that people actually
prefer to pay money for this crap. (</solaris-rant>)
