This example is from the excimer Lab Excercises  Experiment 4

There are two sets of makefiles, one for Metaware on UNIX and one for 
Metaware on PCDOS.
The macros, CC, AS and LINK must all be modified to point to the location
	of the appropriate Metaware tools.
The path on the PC must include a path to the mksnt tools or equivalent
	PC UNIX tool set.
	
	UNIX 	use make 
	PC   	use make -f makedemo_pc
		This makedemo_pc uses the mksnt (Mortise Kern) PC UNIX tools.
		
The lab4.c file exercises the status and error LED's on excimer

	make lab4.src with one of the two commands:

make
make -f makefile_pc

	clean the directory with this command:

make clean

	download and run the program with these commands

dl -k
go 90000
