Overview:

I'm building an SDL application in Go using a sample repository (https://github.com/adam000/go-sdl2-wsl-build-windows) to reproduce the problem. (full repro instructions at veandco/go-sdl2#336 )

I'm building from Windows Subsystem for Linux to create a Windows build (using the bash script in the example). It works for SDL_image version 2.0.1 but not newer versions. On newer versions, it fails with the following message:

Failed to load PNG: Failed loading libpng16-16.dll: The specified procedure could not be found.

I can get newer versions to work simply by replacing the libpng DLL with the one bundled in SDL_image 2.0.1. I noticed that libpng was upgraded after 2.0.1 and before 2.0.2 (revision 518).

Steps to reproduce:

1. On WSL, run ./make-win64-on-wsl.bash from repository root, optionally providing a destination like /mnt/c/Users/myuser/Desktop.
2. Under Windows command line, navigate to the destination and run build.exe

Actual results:

Application crashes with:

Failed to load PNG: Failed loading libpng16-16.dll: The specified procedure could not be found.

Expected Results:

A png of a drawing of a gopher should appear on the screen for several seconds, then disappear.
