The 2 fboundp tests return non-nil when Emacs was built with zlib
support. zlib-available-p can return nil on MS-Windows, when the zlib
shared library is not available, even though Emacs was built with zlib
support. On platforms other than Windows, the fboundp tests and
testing the return value of zlib-available-p are equivalent.
