New versions of libpng aren't supposed to be linked against libz (one uses
'libpng-config --libs' to get the linker options).

The problem is that libz is dlopened with RTLD_LAZY, where it should be
opened with RTLD_GLOBAL (in gimagereadpng.c and gimagewritepng.c).

There's a patch to fix this accessible from the project page
(http://sourceforge.net/projects/fontforge/).  It also dlcloses the
libraries when they're no longer needed.

It's easy to find, since it's the only patch there. :-)
