+ * sysdeps/unix/sysv/linux/sigwait.c (__sigwait): Use
+ INTERNAL_SYSCALL is possible.
+
+ * sysdeps/unix/sysv/linux/i386/sysdep.h
+ (INTERNAL_SYSCALL_ERROR_P): New define.
+ (INTERNAL_SYSCALL_ERRNO): Likewise.
+
* sysdeps/unix/sysv/linux/i386/profil-counter.h (profil_counter):
Add hack to prevent the compiler from clobbering the signal
context.
