The Makefile will now use a script (autoversion.sh) to update version.h, which in turn defines a VERSION string and gets included from common.h. The idea is that version.h normally receives a git-describe based identifier that represents the current checkout. In cases where git might not be available, e.g. for builds from a tarball, the script will instead fall back to a predefined version (that should reflect the most recent release tag).
