Subject: [PATCH] [CSRSS] Enable compilation of raise hard error function call
 code

With introduction of 74e527b, a330b56 and subsequently 2791ecd ReactOS can now properly set IOPL (I/O privilege level) for user mode trusted processes. With that said, enable the compilation of raise hard error function call code back.
