[Insight-developers] template <>

[Kent Williams]

I noticed a warning when I used gcc -pedantic to compile some code that 
uses ITK.  There were a bunch of warnings from gcc:

warning: explicit specialization not preceded by `template <>'

This goes back to itkMetaDataObject.h, and the NATIVE_TYPE_METADATAPRINT 
macro.
That macro is used to define template specializations. I don't believe 
its widely used, and you never see a warning if you don't use -pedantic. 
At the same time, the only reason I could see for adding template <> to 
the template specializations is if there are compilers supported by ITK 
that would choke on that syntax.

So, does anyone know of compilers that wouldn't like template <>?
