Test case (cleaned for -Wall) from Wolfgang's page
Identical (and still failing) test case to that given by Wolfgang Helbig, but
for changes I made to make it compile clean (and still fail) with -Wall:
rearranged procedures to avoid missing-prototype warning; fill in prototype for
main; return value from main; header files.
