note: if I copy two different versions of the QtCore4.dll I built into a directory with just those 2 DLLs:

QtCore4.4.dll (msvc++ 2008)
QtCore4.1.dll (msvc++ 2005)

and run them through Dependency Walker, I get the following expected error message with both:

Error: at least one required implicit or forwarded dependency was not found.

BUT with the one built recently with 2008, I get the additional error message:

Error: The Side-by-Side configuration information for "c:\qtcoreTest\QTCORE4.4.dll" contains errors. This application has failed to start..."

Is there thus a problem with my Qt*.dll's???
