haiku/headers/posix/setjmp.h
Ingo Weinhold fe14a904a8 * Implemented [sig]{set,long}jmp() for PPC. No idea, if it is any good,
but it compiles at least. :-)
* Pulled the architecture specific part out of <posix/setjmp.h> into
  <posix/arch/<arch>/arch_setjmp.h>.
* Moved setjmp_save_sigs.c from the x86 specific implementation into a
  "generic" sibling directory, since it is reusable (and actually used
  by the PPC implementation).
* Added generic/longjmp_return.c containing a function __longjmp_return,
  which is invoked at the end of siglongjmp(), resetting the signal mask
  and validating the return value. It is used by the PPC implementation,
  and should also be used by the x86 implementation, but I'll leave that
  to someone who's motivated enough to also test it. :-)
