Hi. It turns out that a bug in a change in krb5-config introduced in krb5 1.12.1+dfsg-2 caused krb5.h to be treated differently and to be subject to -Wundef. This is fixed in krb5 1.12.1+dfsg-3. I've just uploaded that and confirmed that a pidgin-sipe version that does build -Wundef works against that and fails against the broken version.
If you are maintaining an upstream patch for this issue feel free to drop it. Building either with or without -Wundef should be fine. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
