Can't we get rid of zlib-available-p entirely.
Just replace

   (if (and (fboundp 'zlib-available-p) (zlib-available-p))
       (zlib-decompress-region ...)
     blabla)

with

   (condition-case nil
       (zlib-decompress-region ...)
     ((void-function zlib-not-available)
      blabla))

Hmm... but the above is not recognized by the byte-compiler either, so
you'll still see the spurious warning :-(
The best would really be

   (if (fboundp 'zlib-decompress-region)
       (zlib-decompress-region ...)
     blabla)

but I guess we can't have that because we also want to lazy-load the
zlib shared library, right?
