	#You may need to  "hand-tune" compiler or optimization options,
	#which may be specified by setting the OPT and OPT2 environment
	#variables.  OPT2 is used to compile only the most performance-critical
	#modules and usually will select a very high level of optimization.
	#It should be safe to select an optimization which means "treat all
	#function arguments as restricted pointers which are not aliased to
	#any other object".  OPT is used for less preformance-critical modules
	#and may be set to a lower level of optimization than OPT2.
