-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

-
-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?
