Sure. I guess then this patch should be part of the set of patches
removing SCons, which may or may not be applied at a later date
depending on the outcome of the Great Build System Debate. I asked
another Yhc developer about Make/ who told me as far as he knew this
wasn't being worked on anymore. Is it still being worked on?

I note Make/ contains source for a Haskell based make system. Isn't it
essential that Yhc have a build system that doesn't have Haskell as a
dependency? The Yhc runtime has the big advantage of being a bytecode
interpreter, meaning porting to a new architecture is theoretically a
case of compiling the C runtime using a C compiler, then running the
platform independent Yhc bytecode generated by some other computer.
Henceforth you have a working Haskell compiler on an entirely new
platform having started only with a C compiler. Someday maybe, this
could be an alternative way of boostrapping GHC. Using CMake for
building only means that more than a C compiler, you need a C++
compiler, but you don't need a Haskell compiler (at least to build the
runtime).

The files removed by this patch are Batch.hs and Makefile.bpp, which
seems to be yet another method for building under Windows and written
in a Visual Basic like language. If the other build systems subsume
this (or once they do), shouldn't these files be removed?

Does this mean they are used by the scons based windows build?

It just has Split.hs, which this patch removes, along with the test/ dir.
