--- Comment #46 from Christopher Albert <albert at tugraz dot at> --- We have to be careful with this one. I triggered already one error in a test case when running the full suite and now names like "linux" or "unix" are colliding with variable names. Will post a follow-up patch. This should be carefully tested also in production before being released, as i might break downstream codes relying on CPP macros in subtle ways.
