##
##  Makefile for Standard, Profile, Debug, Release, and Release-static versions of MiniSat
##
##    eg: "make rs" for a statically linked release version.
##        "make d"  for a debug version (no optimizations).
##        "make"    for the standard version (optimized, but with debug information and assertions active)
