+Subject: Stop using _pam_overwrite() in pam_cap.c.
+
+It looks like the Linux-PAM folk have deprecated this macro. Compiler optimization
+is hard to account for: apparently this explicit deletion is no longer
+guaranteed to work. This function was marked deprecated in v1.5.3 of Linux-PAM.
+
+I've replaced its use with memset(). I'm not convinced that that will be honored
+either, but remain hopeful and prefer to leave the code explicit in its intent
+without a deprecation warning messing up the build log. Should some compiler
+optimize it away and it leads to an exploit of some sort, it can be revealed as
+a compilation bug.
