# Makefile (for typhoon/GNU-style make).  Recognized gmake variables:
#
#  DEBUG=1: make debug version (includes asserts and sanity checks)
#  TEST=1: include self-test code in the binary produced
#  ASM=1: create assembly code, does not link final binary
#  EVAL_DUMP=1: make a version that can dump eval breakdowns
#  EVAL_HASH=1: hash eval scores
#  EVAL_TIME=1: make a version that counts cycles spent in eval
#  PERF_COUNTERS=1: make version with perf counters enabled
#  BOUNDS_CHECKING=1: make version with bounds checking enabled
#  MP=1: make version for multi-processor machine
#  DUMP_TREE=1: internal tree dumping version
#  SEE_HEAPS=1: use minheaps in the SEE code
#  OSX=1: build for an Intel-based Apple Mac (omit this for FreeBSD/Linux)
#  USE_READLINE=1: link against the GNU readline library
#  SIXTYFOUR=1: make an X64 binary
#  CROUTINES=1: use the C versions of the asm routines [slower]
#  EVERYTHING=1: everything everything everything everything
