The result I get, with grep-2.5.1a under XP, is: 2, both directly in a cmd
shell and through a bat file. This, and not 3, is also the correct answer,
because the regular expression "/Type /Page[^s]" requires at least one more
character after "Page", and in the line "/Type /Page", there is no
additional character.

You get this result because there is indeed an additional character, 0xD,
before the line ending (0xA). Remenber: under Cygwin, the default is binary
files, whereas under MS-Windows, 0xD0xA is the line ending. If you remove
the 0xD's from example.txt, then you get the same result as above: 2.
What you want can be achieved by:
grep --count -E "/Type /Page([^s]|$)" example.txt
which gives the result: 3
