Hi Radim,

I try to build raster providers branch on Windows with MSVC Express 2008
against dependencies from OSGeo4W (gdal 1.7.3) and get next error:

   Creating library D:\devel\raster\build\src\providers\gdal\RelWithDebInfo\gdalprovider.lib and object D:\devel\raster\build\src\providers\gdal\RelWithDebInfo\gdalprovider.exp
qgsgdalprovider.obj : error LNK2019: unresolved external symbol "int __stdcall progressCallback(double,char const *,void *)" (?progressCallback@@YGHNPBDPAX at Z) referenced in function "public: virtual void __thiscall QgsGdalProvider::populateHistogram(int,class QgsRasterBandStats &,int,bool,bool)" (?populateHistogram at QgsGdalProvider@@UAEXHAAVQgsRasterBandStats@@H_N1 at Z)
D:\devel\raster\build\src\providers\gdal\RelWithDebInfo\gdalprovider.dll : fatal error LNK1120: 1 unresolved externals

Any hints on this?
