Compile error on testpng.c, using GCC11

[IoIxD]

I'm sure there's something on my part that's wrong but I have tried for the entire day to compile this and I just can't. Using GCC 11.2.0 but I've also tried GCC] 6, and 5. Nothing seems to work, and I always get the same errors regarding tilepng.c.

CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

I had to change tilepng.c, tilepng.h, testpng.c, and CMakeLists.txt to get it to compile. How this was last compiled a year ago and was never caught is beyond me.

Not gonna bother making a new repo for a pull requests, I'll just put the files here

tilepng_c.txt testpng_c.txt tilepng_h.txt CMakeLists.txt

(edit: I actually ended up making a fork of the repo anyways for various other reasons)

I totatly forget to update this when I changed the palette code. I will maybe have a look

Should be fixed as it compiles, but it segfault now x)
