What version of GCC or Clang are you using? Do you have anything in the CFLAGS environment variable by any chance?

Guess that warning is now an error by default in GCC14 or something. I'll fix that when I can, but for now you can add -Wno-incompatible-pointer-types to CFLAGS on this line in the Makefile. And make a clean build.
