Compile fail from SVN trunk with VS 2008

I compile the source from SVN trunk ver 708 with VS 2008 but get some error message

qwt_slider.cpp

Seems the issue is coming from function ceil. Please help to solve it. Thanks!

quick fix would be to specify the argument-type explicitely in qwt code, e.g. as taken from my qwt_wheel.cpp (5.2.0)

for ( double tickValue = ceil((double)(loValue / tickWidth)) * tickWidth;

for ( double tickValue = ceil((double)(loValue / tickWidth)) * tickWidth;

Yes, I have a quick fix on two files to solve the compile issue already. Thanks for your help!

for qwt_slider.cpp, modify line 781, 782

const int sdExtent = (int)ceil((double)scaleDraw()->extent( QPen(), font() ));
        const int sdLength = (int)ceil((double)scaleDraw()->minLength( QPen(), font() ));

const int sdExtent = (int)ceil((double)scaleDraw()->extent( QPen(), font() ));
        const int sdLength = (int)ceil((double)scaleDraw()->minLength( QPen(), font() ));

same for qwt_thermo.cpp, modify line 836, 837

const int sdExtent = (int) ceil((double)scaleDraw()->extent( QPen(), font() ));
        const int sdLength = (int) ceil((double)scaleDraw()->minLength( QPen(), font() ));

const int sdExtent = (int) ceil((double)scaleDraw()->extent( QPen(), font() ));
        const int sdLength = (int) ceil((double)scaleDraw()->minLength( QPen(), font() ));
