this used to provide autotools compatibility, but it has not been working for a while. Thus it is IMO better to remove it in order not to mislead people.
The changes are:
- Add new macros PROJECT_VERSION_NAME and PROJECT_VERSION_HASH
in addition to the existing PROJECT_VERSION.
- Add header include guards.
if the 'configure' wrapper is used, you will most likely use
dunecontrol. since duncontrol explicitly passes the paths for all the
dependencies, the "convenience" of the sibling search not wanted in
most cases.
