+
+ Fix loop-detection code, add some minor improvements.
+
+ * README-hacking: Update.
+ * bootstrap.conf: Add sysexits.
+ * build/bootstrap: Synch with gnulib repository.
+ * build/gnulib.modules: Remove.
+ * lib/.cvsignore, m4/.cvsignore, po/.cvsignore: Update.
+ * lib/Makefile.am: Remove unnecessary initializations.
+ * src/authmode.c (anubis_authenticate_mode): Remove a block of
+ code duplicated in transmode.c and replace it with a call to
+ session_prologue.
+ * src/transmode.c (anubis_transparent_mode): Likewise.
+ (string_to_ipaddr, session_prologue): New functions.
+ * src/env.opt: Fix Emacs mode marker.
+ * src/headers.h: Include sysexits.h unconditionally.
+ (session_prologue): New prototype.
+ * src/tls.c (cipher_info): Add missing newline.
