For posting development snapshots, I use:

snapshottime = `date +%Y-%m-%d-%H%M`
snap: README
        echo "#define NAIM_SNAPSHOT \"-${snapshottime} (development snapshot)\"" 
> ${top_srcdir}/src/snapshot.h
        make distcheck distdir=$(PACKAGE)-$(VERSION)-${snapshottime}

release: README
        echo "#define NAIM_SNAPSHOT \"\"" > ${top_srcdir}/src/snapshot.h
        make distcheck



You should be able to use sed or some such to populate a Makefile.am 
variable similarly, perhaps like:

realversion=`grep '$Revision $' < ${top_srcdir}/ChangeLog | sed s/.../`
snap: ChangeLog
        make dist distdir=${PACKAGE}-${realversion}


./configure --help will still display the version as being 0 (or whatever 
dummy value you specify in configure.ac), but everything else should 
behave sanely.

What makes a man great? A man may be great in his aims, or in his
achievements, or in both, but I think that man is truly great who makes
the world his debtor... who does something for the world which the world
needs and which nobody before him has done or known how to do. -- Rupert
