We're now ISO on the plural forms (https://github.com/tinygettext/tinygettext/pull/30), so remove the modified warning. We use boost filesystem as <filesystem> and <experimental/filesystem> are not available on the macOS CI yet. (https://github.com/tinygettext/tinygettext/issues/31) Differential Revision: https://code.wildfiregames.com/D3185 This was SVN commit r24342.
