[Qt-interest] [Issue N257294] Unresolved symbols when linking projects that use ActiveQt

[Constantin Makshin]

(Note: All files listed below can be found in the attached archive.)

1) I build 32-bit, 64-bit desktop and WM5 PocketPC versions of Qt.
The compilation process is semi-automated and performed using  
"compile_msvc.cmd" script.
All used "qmake.conf" files are also customized to use as many  
optimization options as possible and properly handle the situation where  
all compiled versions of Qt reside in the same top-level directory.
Both Qt itself and Qt applications (except AciveQt ones when default  
"qaxcontainer.prf" and "qaxserver.prf" files are used) compile and work  
without any problems.

2) I use wrapper scripts for both QMake (see "qmake32.cmd" and  
"qmake64.cmd") and NMake ("nmake32.cmd" and "nmake64.cmd").
This lets me easily use any of the available Qt and compiler versions from  
any instance of command prompt.

3) No, only Visual Studio 2008 SP1 with Windows Server 2008 SDK.

4) Qt compilation process is described above. It may look somewhat  
[over]complicated, but I'm used to it and, what is more important, it  
works.
