[Qt-interest] Huge object files with Visual Studio Express 2008

[Constantin Makshin]

It's OK because release MSVC builds of Qt use link-time code generation,  
which results in larger object files but better code optimization  
(compiler puts some intermediate code into object files and final  
compilation is done during the linking stage, and since the linker can  
treat all these object files as a one huge piece of code, it can optimize  
it independently of actual data/function locations).
