I've attached the fixed version of the patch. I've tested it on the trunk with

Hi,
because I really dislike the hassle our (almost) flattened header
files cause quite often, I have made a very simple experiment to find

Interestingly even when the preferences are accurate, lra_constraints
completely ignores the preferred/allocno class. If the cost of 2 alternatives
is equal in every way (which will be the case if they are both legal matches
as the standard cost functions are not used at all), the wrong one may be
