There are some ideas about the source tree design.

1. Put Makefile onto top of tree, rather than under src directory.
2. Put Makefile onto src/obj, and build in the src/obj directory.
3. Keep Makefile on src directory, but in the Makefile invoke configure script under the src/build directory (or other name), and build binaries under the directory.
4. Keep Makefile on src directory, and never mind messy *.o files.

Which one do you prefer? or are there some better ideas?
