[Interest] problem building qwt in windows

[caius ligarius]

I installed Qwt4.2.0 to "C:\Qt" folder

I currently have Qt version 4.6.1 installed in "C:\Qt\4.6.1", which I
have been using successfully with VS2008.

Next, to build Qwt I open "c:\Qt\Qwt\qwt.pro" in VS2008 using the Qt
plugin. After this when I try to compile this .pro file I get the
following errors. Any idea what I can do to fix this? (All includes,
libs etc. seem to be correctly configured since I open the .pro file
using the Qt plugin).
