In which case you may not find any "-c" flag mentioned, if you're not
running a system whose "diff" has that option.  Not all systems do.

If your "diff" doesn't, there are a number of alternatives:

	1) get GNU "diff", which I think has "-c";

	2) get a program that I think exists somewhere in some source
	   archive, which acts as a "front end" to a "diff" without "-c"
	   and produces context "diff" output;

	3) if you have 4.xBSD source handy, build its "diff" for your
	   system.
