#    -mh		Generate code for the H8/300H chip.
#    -c 		Compile only
#    -0 		Optimize
#    -ffloat-store	Do not store floating point variables in registers
#			and inhabit other options that might change whether
#			floating point value is taken from register or
#			memory.
#    -g3		The compiler debugging option, followed by the level.
#			Level 3 included extra information.
#    -Wall		Issue warnings.
#    -r 		Elimates the use of built-in implicit rules.
#    -save-temps	Do not delete intermediate files
