 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.
