[paraphrased]
	char *fp = "aplcen!mjr", *ap;

	if (ap = re_comp("aplcen!*")) {
		printf("err - %s\n",ap); exit(1);
	}
	if (re_exec(fp))
		printf("match one!\n");
	if (ap = re_comp("*!*)) {
		printf("err - %s\n",ap); exit(1);
	}
	if (re_exec(fp))
		printf("match two!\n");

Remember, re_comp compiles an *ed*-style regular expression, not a
shell-style file match expression.  Try compiling `aplcen!.*' and
`.*!.*' instead.
