This is a bit bogus because it's been removed from glibc (though not thoroughly) and is never useful on Android (because the system calls in question are compiled out of Android kernels, and SELinux would disallow them even if you weren't running an Android kernel). This also means that on glibc you need to include <linux/sem.h> for this and on bionic you need <sys/sem.h> (and for either if you #include the other file, you won't get this union). Bug: https://github.com/android-ndk/ndk/issues/400 Test: added new test Change-Id: I47f721da77515531f616d6ad8479bfbc9b60ee47
