I suggest you don't use the universal SDK unless you have Visual Studios v6.0.
Secondly, the .c sources files are in the second JKA SDK package, which you can find on all the major jka file servers. The .dll files are the compiled version of the .c files. You'll need a compiler that can do .dll files (like Visual Studios).
