+       selinux-h: improve stub types and add more stub functions
+
+       * lib/se-selinux.in.h: Change security_context_t to a typedef
+       rather than a define, as it's a pointer type and so is better
+       as a typedef to avoid issues declaring multiple variables
+       with the comma operator.  Also add stub for string_to_security_class().
+       * lib/se-context.in.h: Add stub functions for
+       context_{type,range,role,user}_get().

+       ignore-value: prefer GCC version back through 2.0
+       The code didn't match the comments, so I did a bit of software
+       archaeology.  GCC 2.0 seems to support __extension__ and
+       __typeof__, so fix both code and comments to use 2.0.
+       * lib/ignore-value.h (ignore_value): Use __extension__ and
+       __typeof__ for GCC 2.0 through 3.3, too.

+       pty: Activate the signature wrapper of forkpty.
+       The intended preprocessor macro HAVE_FORKPTY is
+       never defined, yet `lib/forkpty.c' depends on it.
+
+       * m4/pty.m4 (gl_FUNC_FORKPTY): At completed analysis,
+       apply AC_DEFINE_UNQUOTED to HAVE_FORKPTY with value
+       $HAVE_FORKPTY for access to wrapper in `lib/forkpty.c'.

+
+       quotearg: don't attempt to store 1 << 31 into an "int"
+       * lib/quotearg.c (quotearg_buffer_restyled): Building coreutils with
+       gcc's new -fsanitize=undefined and running its tests triggered some
+       new test failures due to undefined behavior, all with this diagnostic:
+         lib/quotearg.c:629:62: runtime error: left shift of 1 by 31 places \
+           cannot be represented in type int
+       Rather than shifting "1" left to form a mask, shift the bits right and
+       simply use "1" as the mask.
