+Remove usage of <sys/cdefs.h>.
+
+This fixes autobuild issue: http://autobuild.buildroot.org/results/cbb/cbb2bac69aa0708e587ba9fcd1efcead82e42446/build-end.log
+Libsepol uses cdefs.h which is a internal glibc header.
+This header is not intended to be used by any program and will cause
+compiling against musl (and possibly other c libraries) to fail.
+This patch fixed this issue and replaces all references of
+#include <sys/cdefs.h> and __BEGIN/END_DECLS with the appropriate #ifdefs.
+
+This patch has also been submitted upstream to the selinux github repository.
+https://github.com/SELinuxProject/selinux/issues/19
