Blitz Support : |

Hi,
Sorry for the interruption.
I've been trying to work out why the below code will not compile.
(note: The test suite builds and works okay).
Perhaps I am missing something?
Any assistance for fixing this would be greatly appreciated.
On a different note, usually I avoid "using" a namespace (I would prefer to use "blitz::").
However, I suspect that the following define:
array/stencils.h: #define BZ_END_STENCIL_WITH_SHAPE(MINS,MAXS) }
would not work without the line "BZ_USING_NAMESPACE(blitz)". (As TinyVector is not qualified with blitz::).
Thanks,
Martin
