-/* says: */
-/* This patch adds the new dup3 syscall. It extends the old dup2 syscall by */

-/* O_CLOEXEC flag is added in this patch. The following test must be adjusted */
-/* for architectures other than x86 and x86-64 and in case the */

-/* where, -c n : Run n copies concurrently. */
-/* -e : Turn on errno logging. */
