[Radiance-general] genBSDF and Klems output

[Brandon Andow]

Hi Greg and Radiance List,
Concerning the genBSDF inaccuracies, for windows OS is genBSDF.exe
similarly affected? How about any XML files generated using Window7.4 (I
assume only if the shading layer was made with post Mar2015 genBSDF)? Is
there any plan to update the NREL Radiance win64 release with a corrected
genBSDF.exe?
Best,
Brandon
