Log Message:
* Include <sys/sigtypes.h> rather than <sys/signal.h> in <sys/ucontext.h>.
* Define _UCONTEXT_TO_SIGCONTEXT() and _SIGCONTEXT_TO_UCONTEXT()
  macros for converting a ucontext -> sigcontext and back again.
  These macros in turn use machine-dependent macros _MCONTEXT_TO_SIGCONTEXT()
  and _SIGCONTEXT_TO_MCONTEXT() provided by <machine/signal.h>.

  The conversion process is not 100% accurate, but should be close enough.

  Also note that the mcontext conversion may not be enough for all platforms
  (m68k is a good example of this).  These macros should be used only if
  you really know what you're doing.
