# Build Makefile for GNU Make

# Notes:
#  As of 6 July 2005, the engine should handle optimisations being enabled.
#  If things seem to be going wrong, lower or disable optimisations, then
#  try again. If things are still going wrong, call me.
#   

# Engine options - these may be overridden by game makefiles
#  SUPERBUILD     - enables voxels
#  POLYMOST       - enables Polymost renderer
#  USE_OPENGL     - enables OpenGL support in Polymost
#  DYNAMIC_OPENGL - enables run-time loading of OpenGL library
#  USE_A_C        - enables use of C version of classic renderer
#  NOASM          - disables the use of inline assembly pragmas
#
#  SETSPRITEZ     - set to 1 for Shadow Warrior
