How can I improve this patch such that it will be accepted?
The biggest problem is that the libpng versioning scheme is broken, so
we can't find the proper soname. This will need some more configure
magic.
Looking at
http://www.libpng.org/pub/png/libpng.html and
http://www.linux-foundation.org/en/LibPng
and /usr/include/png.h
I get the impression that the libpng versioning scheme
was cleaned up for the 1.2 series over four years ago.
So perhaps we could just change configure.ac to check
PNG_LIBPNG_VER_MAJOR and make sure it's exactly 1,
and check PNG_LIBPNG_VER_MINOR and make sure it's 2 or greater.
That would let us avoid the old broken libpng's, wouldn't it?
