(sa_signal_handler): Define.
(_INIT_SIG_HANDLER): New macro.
(INIT_SEGV, INIT_FPE): Use it.
* configure.ac (SIGNAL_HANDLER): Use it on alpha*-dec-osf*,
mips-sgi-irix*, *-*-solaris2*
* configure: Regenerate.
* include/aix-signal.h: Refer to AIX.
* configure.host (alpha*-dec-osf*): Enable can_unwind_signal.
(mips-sgi-irix6*): Likewise.
