from 1.2.3
update homepage and license
changes:
- remove 1.2.3.3 patch
- breakdown autotools.patch to configure.ac and Makefile.am, update
src in Makefile.am and use do_configure_prepend instead
- remove README from LIC_FILES_CHKSUM because it duplicates zlib.h
and also causes checksum to change for every release
- remove visibility.patch: the purpose of the patch was to change
"<type> ZEXPORT" to "ZEXPORT <type>", however:
1. the use of ZEXPORT and ZEXTERN have been changed a lot in
zlib, there is no changelog to indicate which version was
the patch based on and its rationale
2. zlib used to set default visibility to `hidden'
(-fvisibility=hidden), and override external symbols with
`default' visibility, it had caused a lot of problems on
different platforms. But starting from 1.2.5, default
visibility is now `default', `hidden' visibility override
has effect only for the correct GCC versions, most visibility
related issues should have already been fixed
http://mail.madler.net/pipermail/zlib-devel_madler.net/2010-April/002045.html
3. as for now, ZEXPORT is used in Win/BeOS only, and can expand
to WINAPI or __declspec(dllexport), both of which should be
put behind return type, so there is no need to patch
In conclusion, the patch is not applicable for the current release,
so it's removed
