So do you agree with this, taken from the geos README (in 3.6.2):

  ### Using the C++ interface (discouraged)

  NB: The C++ interface should not be used directly; the GEOS project
  views it as a bug for another program to use the C++ interface or even
  to directly link against the C++ library.  The C++ library name will
  change on every minor release because it is too hard to know if there
  have been ABI changes.  (The C library uses the C++ interface, but the
  C library follows normal ABI-change-sensitive versioning, so programs
  that link only against the C library should work without relinking
  when GEOS is upgraded.)

  To compile programs against the C++ lib:

      CFLAGS += `geos-config --cflags`
      LDFLAGS += `geos-config --ldflags` -lgeos
      #include <geos.h>

  Basic usage examples can be found in `doc/example.cpp`.


Or do you think something else?  It genuinely seems to me that there are
multiple opinions out there.
