I was under the impression the %n problem was finished.
>From the list above I feel that most of them aren't an issue, specifically the ones showing "conftest: *printf used %n: %d %n". Those are autoconf tests that attempt to detect whether %n is usable, usually without the software actually using the result of the test. textproc/recutils is new to me, I can fix it easily. lang/gpc isn't new to me, I forgot about it. security/gnupg is fixed already security/gpgme,-main is the most important one that needs a fix. > Backout required until those get fixed? Unless my analysis above proves to be wrong, I don't think it needs to be backed out. The port listed above that need fixing will probably be fixed by the time you push out a new snapshot. -- jca | PGP : 0x1524E7EE / 5135 92C1 AD36 5293 2BDF DDCC 0DFA 74AE 1524 E7EE
