cpp: Use #pragma once instead of #ifndef guards

3 * (c) The GHC Team, 1998-2009
4 *
5 * Declarations for various symbols exported by the RTS.
6 *
7 * ToDo: many of the symbols in here don't need to be exported, but
8 * our Cmm code generator doesn't know how to generate local symbols
9 * for the RTS bits (it assumes all RTS symbols are external).
10 *
11 * See wiki:Commentary/Compiler/Backends/PprC#Prototypes
12 *
13 * Do not #include this file directly: #include "Rts.h" instead.
