I ran the test on my Macintosh using Mac C (TM) from Consulair Corp.
The execution time was 2.75 seconds.  For those who are also interested in
compile time, the results were:

	compile 15 seconds
	assemble 11 seconds
	link 44 seconds

These times were obtained using my normal operating procedure, which involves
running with a RAM disk containing a small copy of the system, Fast Finder (TM),
Exec, C, Assembler, and Linker.  The source files, libraries etc. are on one
floppy and EDIT, RMaker, etc. are on the other floppy.  I used an Exec job file
to compile and link.  Timing was started when I pressed the execute button in
Exec.  Thus the times above include application startup and so on.  The complete
elapsed time from starting the compile to having an executable version of the
program was 70 seconds.

While I was at it I decided I might as well make other people jealous by running
the test on the UTS system I use at work (running under VM on an Amdahl 470/V8).
The results were:

execute	UTS % timex -p a.out
	Factoring...
	A factor of 1394761 is 1181
	It took 871 iterations
 
 
	real        0.20
	user        0.03
	sys         0.01

compile	UTS % timex -p cc factor.c
 
	real        2.63
	user        0.33
	sys         0.36

The results reported before were:
	
	Compiler         Computer          Execution time (min:sec.)
	 
	 Aztec              Z80                     2:06
	 Eco-C              Z80                     1:41
	 CI-C86            IBM-PC                   0:22.4
	 DeSmet C          IBM-PC                   0:10.1
	 PCC               Vax 11/780               0:00.4

I think both the Macintosh and the V8 look pretty good on this test.
