#-----------------------------------------------------------------------------
#
#  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)

#-----------------------------------------------------------------------------
# Preamble

# Set UseGhcForCc: this causes the fptools build system to use a different
# set of suffix rules for compiling C code, using $(HC) rather than $(CC)
# and prepending "-optc" to $(CC_OPTS).  NB. must be done before including
# boilerplate.mk below.
