#  This is the Makefile for the runtime-system stuff.
#  This stuff is written in C (and cannot be written in Haskell).
#
#  .c  files are vanilla C,
#  .hc files are "Haskellized-C", compiled using the C compiler and
#      (possibly) the assembly-mangler.  The GHC driver script
#      knows how to compile this stuff.
#
#  Other sorta independent, compile-once subdirs are:
#	gmp		-- GNU multi-precision library (for Integer)
