Yeah, the nightly builds look for pd/autogen.sh and if its found, use
that.  Windows/MinGW can build using that build system, but its not
entirely working yet, so the nightly builds still use
pd/src/makefile.mingw.

I removed the old build system from pd-double.git and pushed the change.
Hopefully that'll reduce confusion.
