I guess reading the small documentation in libexif/configure.in should
be sufficient for the average developer especially now that you have
corrected it:

Applied. Thanks!

No. I quickly read through libexif/ChangeLog and now remember 1 change
that we did between 5.11 (2003/08) and 6.9 (2004/05):=20

2004-01-07  Jan Patera <pa...@us...>

        Thread-safety, elimination of static variables, fixes of memory
        corruption (writing beyond provided space), no more memory leaks
        in mnote, 2 new args of exif_entry_get_value,

That is, a new required parameter has been added to the function
exif_entry_get_value. But that should be the only change since 5.12.

Please forgive me my ignorance, but I never even think about manually
linking programs or replacing old libraries with new ones manually.
"./autogen.sh && make install" usually does everything for me (including
checks for compatibility).
