+ 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.
