Review request for KDE Frameworks.


Repository: kguiaddons


Description
-------

Use std::isnan from <cmath> instead of isnan from <math.h>, as MinGW-32 on Windows does not include the latter.  This keeps the _isnan hack for MSVC, since that compiler doesn't include either standard version :(.


Diffs
-----

  src/colors/kcolorutils.cpp 7df25b3d7acbb65b29513d2139d7b83de53ee4c2 

Diff: https://git.reviewboard.kde.org/r/116866/diff/


Testing
-------

Compiled with MSVC10 (32-bit), MinGW 4.8 (32-bit, Windows native), and GCC 4.8 (Arch x86_64).


Thanks,

Michael Hansen
