It would be nice if we are able to back port fixes from the next master (6.0.0) to RTEMS 5.1 easily. I guess RTEMS 5.1 could be a long term release since all the work for SMP which resulted in a massive re-write of the operating system internals stabilizes now. For the new build system we have to get rid of the preinstall anyway, so we maybe we should move the header files now and already remove the preinstall step in the current build system. File moves make back ports difficult. I think we only need six header include directories:

cpukit/include
cpukit/libnetworking/include
cpukit/score/cpu/$arch/include
c/src/include
c/src/lib/libbsp/$arch/include
c/src/lib/libbsp/$arch/$bsp/include

The header file move in the BSP area is a bit of work.
