[Insight-developers] Handling Floating Point Exceptions -- Implementation Questions

[Bill Lorensen]

I suggest a class that does it ala vtkFloatingPointExceptions. Just
isolate all the ifdef junk in a similar class. I don't follow why that
won't work. Why change KWSYS?

Or we can keep supporting the Borland compiler which has done a great
job of uncovering floating point exceptions for 10 years in ITK.
