-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

-its include path, which is the same file that declares siginfo_t.

-OK to commit?  This should probably also go into any active release
