OSSstatus / OSSlib.h & the gnu/linux kernel

Hi guys!

A little question,
The OSSstatus variable that is used on OSX and vxWorks ( http://www.dholloway.com/vxworks/6.5/man/cat1/ossLib.shtml), is defined under a file called OSSlib.h and is not provided, in the gnu/linux kernel… as you can see there: http://patchwork.kernel.org/patch/7014/

Some OF projects developed with OSX, uses that variable…

How to avoid that?
Everyone knows a valid alternative to OSSstatus?
Everyone knows how to add OSSlib.h and its dependencies to a project and where to find it?

Thanks!
