This directory contains a version of the stack development with
the following components:

stack.[ch]: joke stack, can only store 0 or 1 elements successfully.
test1.c:    first test case using CHECK_* macros
test2.c:    second test case using CHECK_* macros
test3.c:    third test case using CHECK_* macros
test4.c:    refactored fourth test case
Makefile:   fully functional Makefile to compile and test test1..4
checker:    fully functional perl script
bool.h:     basic boolean type
check.h:    the CHECK_* macros

RESULT:     tests 1..3 pass.  test 4 still fails, showing the joke
	    stack is.. laughable!
