I have two suggestions to how the git repository is organized:

(1) There is toplevel rwhoisd directory. It's unnecessary. Could you move all the file one level up and remove the rwhoisd directory so that configure.ac is directly at the top of the git repository?

(2) The repository tracks generated file like "configure" file. This is wrong because once you touch configure.ac, the configure file will become invalid and it changes a lot and that will produce hard to read patches as they will contain generated lines. Please remove the generated files (./configure, ./regexp/Makefile) from the git repository.
