qHash(double) problem with Qt 4.6 (tp1)

[Uwe]

I tried to comment out the line, still getting the same compilation error...

Then try harder: a compiler can't fail at a line, that has been removed.

More explicite: the offending line is the line exporting the template, but you can remove the complete QWT_TEMPLATEDLL scope ( or use qwt_valuelist.h from SVN 5.2 branch. )
