This is a partial backport of the following change to libgcc:
2012-04-20 Thomas Schwinge <thomas@codesourcery.com>
struct siginfo vs. siginfo_t
* config/alpha/linux-unwind.h (alpha_fallback_frame_state): Use
siginfo_t instead of struct siginfo.
* config/bfin/linux-unwind.h (bfin_fallback_frame_state): Likewise.
* config/i386/linux-unwind.h (x86_fallback_frame_state): Likewise.
* config/ia64/linux-unwind.h (ia64_fallback_frame_state)
(ia64_handle_unwabi): Likewise.
* config/mips/linux-unwind.h (mips_fallback_frame_state): Likewise.
* config/pa/linux-unwind.h (pa32_fallback_frame_state): Likewise.
* config/sh/linux-unwind.h (shmedia_fallback_frame_state)
(sh_fallback_frame_state): Likewise.
* config/tilepro/linux-unwind.h (tile_fallback_frame_state): Likewise.
* config/xtensa/linux-unwind.h (xtensa_fallback_frame_state): Likewise.
