I'm not entirely sure if the changed symbols are part of the public API,
so I'll be conservative and assume that the library is incompatible.

I've pushed a gcc5 branch with changes to append v5 to the library
package names, but I don't think I'll upload these changes to
experimental soon.

The GEOS 3.5.0 release is expected in the near future, so we may not
need the v5 renames and tag along with the new SONAME. But that assumes
GCC 5.2 is moving from experimental to unstable soon. In what time frame
do you expect the switch to GCC 5 to happen in unstable?

Kind Regards,

Bas
