+dnl * Check for sa_handler in struct_sigaction. The very fact that this
+dnl definition is present or missing signifies whether or not the rt_sig*
+dnl syscalls exist and are implemented on the target architecture, as the
+dnl sigaction(2) call obscures this point in glibc. This doesn't signify
+dnl whether or not the RT signals function though -- those must be proved
+dnl through functionality tests..
