In this case your BSPs should include <bsp/default-initial-extension.h> in 
<bsp.h>.  This <bsp/default-initial-extension.h> defines also 
BSP_INITIAL_EXTENSION which is used by <rtems/confdefs.h>

No, it is intended that <bsp.h> includes <bsp/default-initial-extension.h> if 
this BSP uses the shared bspclean.c.

Yes, this stuff is improvable.

Yes, global functions without exactly one declaration in a header file per 
architecture are broken.
