Firstly. I would like to thank Alexey for reporting this and providing the patch. A good job. Thank You, Alexey.

I have no idea what ShutterCount is. So I'm accepting Alexey's code in good faith. For sure it has made a difference and has not broken the test suite.

I've also made some minor formatting changes to the code. In particular, I've removed Author and other credits as that information is stored in SVN.

I've extracted the metadata from one PEF and one DNG and added them to the test suite:

626 rmills@rmillsmm:~/gnu/exiv2/trunk $ dir test/data/RAW*
-rw-r--r--+ 1 rmills  staff    59K  9 Sep 09:13 test/data/RAW_PENTAX_K100.exv
-rw-r--r--+ 1 rmills  staff   9.2K  9 Sep 09:12 test/data/RAW_PENTAX_K30.exv
627 rmills@rmillsmm:~/gnu/exiv2/trunk $
And lastly, thanks to Alexey for fixing the unused variable in easyaccess.cpp. Perhaps I should have opened another issue to deal with that, however I have not done this to save my time.

I am closing this issue as it has successfully built on M/L/Cygwin/MinGW and Visual Studio.

http://exiv2.dyndns.org:8080/job/Exiv2-trunk/2619/

There's a lot of grumbling coming from the test suite concerning WebP, ICC and other stuff which isn't related to this issue. The trunk builds and passes OK when I build manually (on my laptop and/or buildserver desktop). I'm undertaking buildserver maintenance at the moment to start publishing a daily build for MinGW/32. I'll investigate and fix the buildserver. These buildserver/test issues have nothing to do with the changes submitted in this issue.
