Suggestion: Use EditorConfig to help us stick to our coding style.
Merge branch 'master' of https://github.com/taglib/taglib into develop
Removed editor config file.
Added new defines to quiet some compiler warnings.

Fix local variables overshadowing other ones.
Fixed unused method in release builds.
