Andi, if you feel the need to add explanations before giving the link, probably the link is not giving enough information. Could you instead add these explanations to the wiki so in the future we can just say: Please, see http://gcc.gnu.org/wiki/FAQ#configure_suffix The goal of the FAQ should be (1) to save time and (2) to have a standard and correct answer. Cheers, Manuel.
