I'd remove dot in the end.
I don't like 'when', but I don't know anything better.

This should be on single line.

Other proposed changes:

* PATH_MAX is in limits.h + we usually don't put comments why it's included:
-#include <sys/param.h>	/* for PATH_MAX */
+#include <limits.h>

* use size_t in setup
 static void setup(void)
 {
-	unsigned int n;
+	size_t n;

BTW it'd build just with #include "tst_test.h", because all 4 headers are
included by headers which tst_test.h includes.

I guess most of that it applies to your patch unlink08.c as well, could you
please send v2?

Kind regards,
Petr
