There is no native vs. compat on the SPU. The COMPAT_ bit refers only to
32-bit or 64-bit processes on the PPU.
However, there are some system calls which the SPU may execute, and
other system calls which it may not (usually those involving signals).
Looking back at it, I'm not entirely sure the above description is
actually going to help your confusion... I recommend just looking at the
places that systbl.h is included, and what the macros expand to in each
case.
