I marked it as a regression according to the submitter's remark "so this
library cannot be compiled any more for i686". I didn't actually check,
but the problem sounded severe, so that I marked it as a regresion
anyway, just to be sure that it gets attention.
I should have been more explicit about that, sorry.
