I have opted not to use autoconf for the build process for sprite32, for reasons of simplicity and efficiency (or autoconf's lack thereof in this regard for small projects like this).

Currently, building sprite32 requires editing the config.mak file in this
directory to customize the library for your OS and which renderer you want.
Complete directions are inside the file's comments.

Once config.mak is the way you want it, do a "make" and then a "make install"
as normal.
