+Subject: [PATCH] Replace 'struct siginfo' with 'siginfo_t'.
+
+glibc 2.16 will remove the undocumented definition of 'struct siginfo'
+from <bits/siginfo.h>.
+
+This change is already present in glibc 2.15.90, so qemu compilation
+of certain targets (eg. cris-user) breaks.
+
+This struct was always typedef'd to be the same as 'siginfo_t' which
+is what POSIX documents, so use that instead.
