[geos-devel] Interface changes

Yes please, add the version info - I think I originally put it at the
very start of configure.in, with a matching AC_SUBST at the end - that
should take care of it for geos-config and should propagate to the
object files through a gcc command line define. Maybe I just thought I
put it there :)

One point about version numbers: the geos.m4 macro file that I added to
the distribution (which defines GEOS_INIT(version) to be used in
configure.in by any automake-based program that wants to check for geos)
depends on having all three version numbers, and will not work correctly
with two. So if we want that to keep working, we should have 1.4.0, not
1.4, or the m4 macro should be made smarter (probably a better idea).
