 * Declarations for various symbols exported by the RTS.
 *
 * ToDo: many of the symbols in here don't need to be exported, but
 * our Cmm code generator doesn't know how to generate local symbols
 * for the RTS bits (it assumes all RTS symbols are external).
 *
 * See wiki:commentary/compiler/backends/ppr-c#prototypes
 *
 * Do not #include this file directly: #include "Rts.h" instead.
