[Qt-interest] version of VS 2008, used for building official qt

[Sergey]

Hello,

ftp://ftp.troll.no/qt/source/qt-win-opensource-4.7.3-vs2008.exe
built using VS 2008 without SP1

QtCore.dll from this distribution contains manifest with line:
 <assemblyIdentity type="win32" name="Microsoft.VC90.CRT"
version="9.0.21022.8" processorArchitecture="x86"
publicKeyToken="1fc8b3b9a1e18e3b">

If i install VS 2008 SP1, i get 9.0.30729.1 version in executable manifest.

Why official qt built with VS 2008 without SP1?

Must i install VS2008 without SP1 to build my QT programs using QT
from ftp://ftp.troll.no/qt/source/qt-win-opensource-4.7.3-vs2008.exe?

If i install VS 2008 SP1, can i build executables with 9.0.21022.8 in manifest?
