Everyone kept saying, "don't check the output in configure, check the return code".  Sigh.

Anyway, I think I have fixed this by requiring gcc 4.0 or later when __APPLE__ is defined in order to use the visibility attribute.

I'm also multiplying __GNUC__ by 100 now, instead of 10.

Please pull the latest patch from https://github.com/madler/zlib/tree/develop and let me know how it works.  Thanks.
