While trying to compile BFL using the debian package of newmat, I
encountered this error which running make check

../../../../src/pdf/test/test_gaussian.cpp:69: error: no match for

Indeed, it appears that the operator[] has disappeared from the matrix
and vector wrapper classes?
I don't know yet why the error occurred only now (maybe because I used
the debian matrixwrapper package until now), but if the operator[] is
not defined in matrix and vector_wrapper.h, we shouldn't use it in
(portable) tests I guess...
So unless I forgot something, I consider this a bug.

Klaas
