[Insight-developers] Dashboard Cleanup: mini0.nlm MacOSX-cross-rosetta : 50 tests failing

[Gordon L. Kindlmann]

Hello,

Its actually a subtler issue; a disagreement about whether the 22nd  
bit of a 32-bit float should be 0 or 1 in a quiet (versus signaling)  
NaN.  Different architectures do it different ways.  Surprisingly, its  
orthogonal to endienness.

I'm trying to catch up on the emails related to the NRRD updates to  
see what might have gone wrong.
