Yes, it's clear.

On the contrary, depending on the ./configure is actually the strength
of the solution.
Every svn update should be followed by ./configure, then make,
and skipping ./configure after svn update should not be supported whatsoever.
The svn update can bring lots of things changes at different levels
and users shall never
assume build configuration, templates of generated headers, and other
will stay untouched. After svn update, all dangling headers, generated
calls to ./configure should be regenerated.
Any workflow within the development version of source code different than
svn update && ./configure && make
should neither be encouraged to follow, nor supported.
Also, geos/version.h should have something like
#define GEOS_REVISION @GEOS_REVISION@
substituted during boostrap.
My 5 cents.

This is not a solution, but obscure hack that interferes with typical
My 2 cents.
