      Hi, Everyone,

      Got error while building Qt using Mingw-w64:

      because Mingw-w64 winerror.h doesn't contain appropriate definition. After fixing it (using code from https://github.com/wine-mirror/wine/blob/master/include/winerror.h ), next error appeared:

      Reproduced for Debug+shared and Release+<shared,static> configurations.

      It appeared after patch 155554 was merged to Qt-5.7 branch with recent update. Probably because some DirectWrite 2 functionality (like IDWriteFontFace2 interface) was not ported yet to Mingw-w64.

      Temporary solution could be to disable automatic build of directwrite2 for Mingw-w64, until missing functionality would be implemented in it.
      Or add -directwrite2 and -no-directwrite2 options to file qtbase\tools\configure\configureapp.cpp, so Mingw-w64 users could bypass this error via configuration parameters.

      UPD: While -no-directwrite option disable both DirectWrite and DirectWrite 2 support, DirectWrite 2 remains marked as enabled in configure.exe output:

      Configuration:
...
    audio-backend
    directwrite2
    native-gestures

QMAKESPEC...................win32-g++ (commandline)
...
DirectWrite support.........no
DirectWrite 2 support.......yes
Use system proxies..........no

      That's a minor flaw, but it confuses a little.

      Regards,
      Alexander
