X-Git-Tag: qt-v5.0.0-alpha1~3872
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6f4212e5936b96a8be0eacddbfc4dd7ca5abd776;p=profile%2Fivi%2Fqtbase.git

Fix QString/QByteArray literals for MSVC2010 (compilation of tests).

- Specify return type of QByteArrayLiteral/QStringLiteral lambdas.
- Define QT_UNICODE_LITERAL instead of QT_UNICODE_MARKER.
