+* support/suexec.c: Add gcc format-string attributes to logging
+  functions.  
+  (main): Always print uid/gid as unsigned long, and cast to avoid
+  warnings (which somewhat defeats the point of the format string
+  attrs, but is necessary since the size of gid/uid varies).
+http://svn.apache.org/viewvc?view=revision&revision=1337344
+
+
+
+suexec: Add support for logging to syslog as an alternative to a
+logfile.
+
+* support/suexec.c (err_output) [AP_LOG_SYSLOG]: Log to syslog.
+  (main): Close syslog fd if open, before execv.  Add -V output
+  for AP_LOG_SYSLOG.
+
+* configure.in: Add --with-suexec-syslog argument; allow
+  --without-suexec-logfile to omit definition of AP_LOG_EXEC.
+
+http://svn.apache.org/viewvc?view=revision&revision=1341905
+
+
+
+suexec: Support use of setgid/setuid capability bits on Linux, a
+weaker set of privileges than the full setuid/setgid root binary.
+
+* configure.in: Add --enable-suexec-capabilites flag.
+
+* Makefile.in: If configured, use setcap instead of chmod 7555 on
+  installed suexec binary.
+
+* modules/arch/unix/mod_unixd.c (unixd_pre_config): Drop test for
+  setuid bit if capability bits are used.
+
+* docs/manual/: Add docs.
+
+http://svn.apache.org/viewvc?view=revision&revision=1342065
