Hmm, always inline is bad too. As gcc allows in debugging build to
omit inlines, which allows debugging even of those.
I think it would be a better solution to provide an additional
intrinsic library for making gcc compatible to VS. I don't like to see
this force-inline in headers as it has the tendency to hide stuff and
makes function pointer passing of those functions not correct working,
as each module gets an new version of this intrinsic.
