+There is one usage in boehm-gc/os_dep.c, but it is only used if
+SUNOS5SIGS is defined, which it is only if one of SUNOS5, DRSNX, HPUX, or
+FREEBSD is defined, which are all not using Linux-based glibc ports.
+
+Likewise, gcc/ada/init.c has a struct __siginfo occurence, but only for
+__FreeBSD__.
+
+config/rs6000/linux-unwind.h uses ``char siginfo[128]'', and
+config/s390/linux-unwind.h also uses a constant.
+
+I tested the following patch for sh-linux-gnu.  This only covers one
+configuration, but the change is pretty mechanic anyway and every place
+that used to refer to struct siginfo already must have had <signal.h> in
+its include path, which is the same file that declares siginfo_t.
+
+OK to commit?  This should probably also go into any active release
+branches, to keep them buildable once this glibc change ripples through?
+
+libgcc/
+        * 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.
