A little rush of mine.

Ok.

Thanks to clarify that.

The 2.5.9-2 seems to be ok (on sid). This chat would
result in 2.5.9-3.

The option started to be used in version 2.4.1-1 (2008),
I believe. From debian/changelog:

* New upstream release (Closes: #480127):
     - Not bumping shlibs, no new symbol.
     - To achieve this, use two dh_makeshlibs calls (one for
       libgphoto2-port0 and one for libgphoto2-$(major), and provide with
       the last upstream version sharing the same ABI. Using 2.4.0 here
       although some former versions might have been specified. That
       shouldn't make any difference from a testing migration point of
       view.

Do you know when the .symbols file started to be in use ?

I did a build without the '-V' option. I don't see errors
messages.

My objective is to do a clean on the package control files
(e.g. it had maintainer scripts doing nothing for some years).
