    Description

      I checked out the v5.14.0-alpha1 tag and built Qt on Windows with VS.net 2017 using the following configure options:

      configure -release -platform win32-msvc2017 --commercial -confirm-license -nomake examples -nomake tests -ltcg -qt-zlib -directwrite -mp

      QtGui fails to link, with the same kind of unresolved externals for QVector<QPoint> described in QTBUG-78112.

      If I configure without -ltcg, it works.

      If I remove the line that includes qvector_msvc.cpp from tools.pri, it works.

      If I build with VS 2019, it works (with or without qvector_msvc.cpp, seemingly).
