Hello Ralf,
thanks for the nits, as pre-checkin they come to late. How about
checking them in yourself? The patch is hereby preapproved.

The latter happens if one does copy and paste without really reading the
copied sentences. The following should be corrected as well:
| -Warray-temporaries
| Warn about array temporaries generated by the compiler. The

| in optimization, in order to avoid such temporaries.
in -> for optimization.
