Cool :)

This is wrong. No emulation should depend on any other. An emulation
should only depend on mainstream system calls, should not even
require any COMPAT_?? - the necessary code should be brough up
so that it's emulation-specific, via some includes and defines.
While the emulation code is not quite clean WRT COMPAT_??, there should
not be more implicit dependencies added.
