BUG: Visual Studio itkClampImageFilterTest failures.

BUG: ITK unable to detect number of threads under Unix in recent glibc.

COMP: Missing return error after exception

VS 2010 complains when a function that throws an exception does not
return a value. Some other VS compilers may warn rather than error.

Typical error:
error C4716: 'itk::Transform<double,3,3>::TransformVector' : must
return a value
