[Interest] Compilation of Qt 5.2 winextras fails on Windows

[Adam Light]

Hi

I am trying to build my own version of Qt 5.2 from a Git checkout, but I'm
getting compiler errors in the winextras module.

I followed the instructions in the"Getting the source code" topic at
http://qt-project.org/wiki/Building-Qt-5-from-Git.

I'm using Windows 7 64-bit with the VS2008SP1 compiler and with the Windows
7 SDK installed. I have previously successfully built Qt 5.1-beta1 using
this same configuration.

I am using the following configuration command executed from a Visual
Studio command prompt:
c:\qt5test\qt5>configure -confirm-license -debug-and-release -opensource
-gui -widgets  -no-qml-debug -nomake examples -nomake tests -no-sql-mysql
-opengl desktop -make-tool jom

When I execute "jom", and wait for quite a while, I eventually get these
error messages:

If I re-run configure and add the "-skip winextras" parameters, and then
run jom again, I am able to build successfully.

The combination of Windows 7 and MSVC 2008 is not listed as supported at
http://qt-project.org/doc/qt-5/supported-platforms.html. Has anyone else
run into this problem?

Thanks
Adam
