Three conditions need to be known and haven't been supplied.
Full path of current working directory.
Full path of script1.
Full path of required script2.

That's all fine if the CWD contains a dir 'includes' which holds script2.

The point here is he said this worked on UNIX. That would be impossible
unless the script was in / which we can be pretty sure it wasn't cause
/ normally would contain only mounted FSs (eg: usr/etc/home/var).

Correct.

An arbitrary choice IMO.

You mean the first 8 variants without the 'includes/' part.

That's easy. You're supplying a path relative to '.' so it won't try
to find script2 in lib dir. You have to leave './' off or use a path
relative to lib dir:
lib 'C:/mystuff'; # which has an includes dir in it
require 'includes/28esp.pl'; # should work
lib 'C:/mystuff/includes';
require '28esp.pl'; # should also work
