hi, Tim
After some quick and dirty modification for missing posix environment, 
functions, invalid keyword usage and ambiguous call, I finally made 
libosmscout compiled under msvc8. Then, I tried converting a small osm 
file(<500KB), but the importer crashed for invalid superscript access of 
std::vector in last several lines of bool 
NumericIndexGenerator<N,T>::Import(...), writer.Write(pageStarts[0]); So 
I added a if statement to avoid such case. This time, the importer ran 
without errors. Then I tried using the newly added osmscout to view the 
map, but get nothing at all.
However, according to the screenshot, the display quality of libosmscout 
is amazing ,almost close to mapnik, but still have some label placement 
issues. Cario has been slower than GDI+ under windows for a long time. 
QPainter is just slow for such heavy job. The multi file organization 
will also exhaust lots of system resource on mobile platform.
It will be also grateful, if you could solve these posix environment 
dependent issue to make libsomscout more portable.
