The cgen framework provides a "VOID" type for code to use, but this
defines ends up conflicting with the standard Windows VOID define.
Since they actually define to the same thing ("void"), undef it here
to fix the Windows build.

We might want to reconsider the need for "VOID" in cgen, but that
will take larger discussion & coordination with the cgen project.
