* system-solaris-x86.ads (ZCX_By_Default): Switch to True.
(GCC_ZCX_Support): Switch to True.
* s-intman-solaris.adb (Notify_Exception): Call
Adjust_Context_For_Raise before raising, as expected for signal
handlers in general.
* s-intman-posix.adb (Notify_Exception): Remove declaration of
Adjust_Context_For_Raise, moved to the spec of this unit to be visible
to other implementation bodies.
* s-intman.ads (Adjust_Context_For_Raise): Declare and import here, to
be visible by multiple implementation bodies.
* init.c [VMS section] (__gnat_handle_vms_condition): Adjust context
only for conditions coming from hardware.
[alpha-tru64 section] (__gnat_adjust_context_for_raise): Implement,
adjustments to signal context prior to exception raise from signal
handler.
(__gnat_map_signal for VxWorks): Map SIGSEGV to Storage_Error in RTP
mode.
Solaris section: (__gnat_adjust_context_for_raise): New function.
Implementation of the machine context adjustments to perform prior to
raise from a signal handler. Version for both sparc and x86.
(HAVE_GNAT_ADJUST_CONTEXT_FOR_RAISE): Define.
(__gnat_error_handler): Expect a third argument, ucontext_t *. Adjust it
prior to raising as expected for any handler, before possible nested
faults to make sure all the contexts in a chain have been adjusted by
the time we propagate.
