Yes, I've noticed that lots of modifications have been done. Now, I can 
get rid of the use of boost lib and those ambiguous call.
Some minor issues:
1.CitySearchDialog.h loses a header guard.
2.Missing of build tool generated headers under msvc, (currently simply 
commented out).
3.MapPainterQt.cpp uses log2() which is missing in msvc (I see the 
Log2() in Util.h, and use it instead)

Yes, the importer also works under msvc8.

Under debug mode or release mode? You may try turning off the debug 
iterator 
support(http://msdn.microsoft.com/en-us/library/aa985982%28VS.80%29.aspx)

Generally, qmake can generate the corresponding vcproj from qmake proj, 
but it is not so convenient(these mocing stuff). The best way to make 
use of Qt under msvc is using the Qt vs addin, but currently no vs2010 
support and won't work with express version.
The official site offers a pre-built lib built by msvc9. You may use it 
with vs2010, but the debug lib will be invalid.

Yes, tested under msvc8/9 with test.osm.
Some issues:
1. While panning the canvas, sometimes it won't do the redraw. The 
canvas is just moved along mouse drag.
2. Crash while zoom to some level. According to debugger, it comes from 
AreaNodeIndex::GetNodes() on line 96. The iterator debugging gives 
"map/set iterator not dereferencable".

Good job.

I'd also expect a Qt based TravelJinni or OSMScout with routing feature.
