[Insight-developers] API change of vnl_math to namespace

[Matt McCormick]

Hi,

Recently, changes were made in vnl_math.h so that vnl_math_abs is now
vnl_math::abs, etc.

This is causing pain in ITK :-(.

What is the recommended way to deal with this change in a
backwards-compatible way?  I could not find pre-processor version
definitions in core/vnl/vnl_config.h or core/vxl_config.h

Thanks,
Matt
