That patch won't be needed in this case. if doesn't specify
-export-symbols-regex option, libtool will do export all
symbols.
For this issue, I don't remember why I added those packages
to Depends(perhaps from discussion with Marcelo?), if some
applications depends on gtk+2.0 and uses some png file but
doesn't link libpng directly, libpng3-dev isn't needed to
build such applications. I mean libpng3-dev is just needed
to build the applications/libraries which depends on libpng
directly.
I think adding libpng3-dev to Build-Depends in the
applications/libraries which actually needs it is enough.
so we may remove libpng3-dev from libgtk2.0-dev's Depends.
