Hello dw,
That's my problem - it just does not work. The __attribute __ ((optimize ("no-tree-vectorize")))
works ONLY for NON-inline functions / methods. With inline functions / methods, it is ignored by
the compiler - there this attribute must be set already in the surrounding context. However, I am
working on a generic library. Since I can not require that the user sets various compiler-specific
attributes this to work them properly.

thx
