The most likely explanation is that you are using a Cygwin DLL and you have a conflicting one on your system. If that is the case ldd will tell you what is wrong.
Where did you obtain the build of libpng? If you built it yourself, how did you build it (what options, if any, to configure) and how, where and what did you install?
When you build your app what do you link against, and what does ldd say your app requires?
