OK, why is it 8 byte aligned? Checking.... > revision 1.108 > date: 2011-01-18 20:52:24 +0100; author: matt; state: Exp; lines: +2 -1; > Make struct disklabel 8 byte aligned.

I think I proposed to change the loop to 8 byte increments back then, but noone knows what odd systems it will the stop working on (none at all is my personal bet). So I guess your patch is the best way forward. Martin
