The Debian package of 3.2.41, which included these two patches, built on mips and ia64. (Actually it failed on ia64, but *compilation* was successful.) (This does not, of course, prove that I didn't un-fix the information leak.) Here is the first patch again (separate versions for 3.8.y and for earlier series), now with a more accurate subject line. I'm going to include this in 3.2.42. Ben. -- Ben Hutchings The two most common things in the universe are hydrogen and stupidity.
