the "in_le32" funcs (and all the other related "le32" helpers) never
made it into the common Linux API and many
ports (such as the Blackfin arch) never defined them.  so it fixes
building for all the ports which lack "in_le32".  i dont have a source
tree by me atm, but i'd imagine that this is most arches.
