#  This is the Makefile for the runtime-system stuff.
#  This stuff is written in C (and cannot be written in Haskell).
#
#  We create two libraries.  One, libHSrts<tag>.a, is built separately
#  for each "way".  The other, libHSclib.a is built once: it is just
#  .lc files that end up the same no matter what, i.e. completely
#  ordinary C.

#  Other sorta independent, compile-once subdirs are:

#	gmp		-- GNU multi-precision library (for Integer)
