I like the following:

	#define ISPREFIX(s1, s2) !strncmp(s1, s2, strlen(s1))

It isn't clean, it isn't efficient, but it makes

	if (ISPREFIX("command1", cmdbuff)) {
		...
	} else if (ISPREFIX("command2", cmdbuff)) {
		...

reasonably clean. It refers to s1 twice, and it isn't fully
parenthesized, but it works for this limited application.

Now, somebody want to post a version of the notorious bit-table macros?
God, I wish spell(1) weren't proprietary, those are REALLY cute!
