[Qt-interest] Compiling Qt 4.7 with LTCG

I am having difficulty compiling Qt 4.7.3 with Visual Studio 2008 SP1 on
Windows 7 with LTCG.  I am using the following parameters to configure Qt
before building:
configure -opensource -debug-and-release -platform win32-msvc2008 -ltcg -mp

I receive the following error:
fatal error C1047: The object or library file
'c:\Source\Qt\4.7.3-32\src\tools\bootstrap\release\bootstrap.lib' was
created with an older compiler than other objects; rebuild old objects and
libraries

Here is what Microsoft has to say about it <
http://msdn.microsoft.com/en-us/library/ms173554(v=vs.90).aspx>.

Obviously, bootstrap.lib was created with the same compiler because it is
being build during the same make process. I am using a fresh copy of the
source code so that no temporary files exist before building.

Thank you for your help,
Sean
