Compilation fixes for MSVC (2013)
Review Request #127177 - Created Feb. 25, 2016 and submitted
Fix compilation on Windows with MSVC.
a) MSVC accepts declspec at global scope, only.
b) QStringLiteral does not work with concatenated literals in MSVC (see http://blog.qt.io/blog/2014/06/13/qt-weekly-13-qstringliteral/). Since the occurences seem to be mostly for debugging, going through QString::fromLatin1() in these cases should not hurt much.
Now builds with MSVC 2013.
No other compilers and no other platforms tested for this patch.
