A simple solution that may work or blow up: rename libpng.dll to
libpng12.dll. That version might conflict with GTK's. The name of the
DLL is (at least for MSVC) coded in the .lib import library.

Microsoft "recently" introduced the concept of manifests to describe
which version of a DLL to use. 

But I think this only applies to the DLLs in the Side-by-Side assembly
(The infamous WinSxS directory) which contains mostly the MS runtime
stuff.

Welcome to DLL hell.
