Subject: [PATCH] use tx as the type specifier instead of zx

A couple of printf() commands use "zx" as a type specifier for printing
a difference of 2 pointers. "z" means a size_t, but using "t" which is
ptrdiff_t is correct. The issue was found on s390 (32-bit) where size_t
is defined as "unsigned long" as opposed to the usual "unsigned int".
