Subject: [PATCH] [project @ 1999-03-03 19:26:31 by sof] COMPILING_RTS is now
 defined when compiling the rts. It is used for the
 following:

 - the contents of includes/Prelude.h is only visible when COMPILING_RTS
   is on.
 - getting the DLLIMPORT declarations right on various labels defined by
   the Prelude or the RTS.
