+
+ intprops.h: adjust comment to match code change
+ * lib/intprops.h (_GL_INT_CONVERT): Adjust comment: now that E is used

+ test-intprops: disable -Wtype-limits diagnostics
+ * tests/test-intprops.c: Use a pragma to ignore -Wtype-limits

+ intprops: shorten, to pacify gcc -Woverlength-strings
+ * lib/intprops.h (_GL_INT_CONVERT, _GL_INT_NEGATE_CONVERT):
+ (_GL_BINARY_OP_OVERFLOW): Say "0 * (x)" rather than "(x) - (x)",
+ so that, for example, verify (INT_MULTIPLY_OVERFLOW (...)) is less

+
+ utimensat: do not reference an out-of-scope buffer
+ Otherwise, with __linux__ defined, "times" would point to a buffer, "ts"
+ declared in an inner scope, yet "times" would be dereferenced outside
+ the scope in which "ts" was valid.
+ * lib/utimensat.c (rpl_utimensat) [__linux__]: Move the declaration
+ of ts[2] "out/up", so that the use of aliased "times" (via
+ "times = ts;") does not end up referencing an out-of-scope "ts"
+
+ opendir-safer.c: don't clobber errno; don't close negative FD
+ * lib/opendir-safer.c (opendir_safer):
+ [HAVE_FDOPENDIR || GNULIB_FDOPENDIR]: Don't close a negative
+ file descriptor, and more importantly, don't clobber the
+ offending errno value with EINVAL. Before, upon failure
+ of dup_safer, we would pass the negative file descriptor to
+ fdopendir, which would clobber errno.

+ maint.mk: more tight_scope improvements
+ * top/maint.mk: (_gl_TS_var_match): Use $(_gl_TS_extern) here, too.
+ (_gl_TS_headers): Define only in if-0'd block.
+ (_gl_TS_dir): Omit the $(srcdir)/ prefix. Sometimes we need it,

+ (sc_tight_scope): Use much simpler grep-based test to determine
+ whether we skip this rule.
+
+ maint.mk: generalize/improve the tight-scope rule
+ * top/maint.mk: Emit a warning when the test is skipped.
+ (_gl_TS_dir): Add $(srcdir)/ prefix.
+ (_gl_TS_function_match): Simplify, rather than trying
+ to enumerate common types. Otherwise, it would fail to match an

+ (_gl_TS_extern): Do not endorse use of "XTERN", but do provide
+ a way to support use of that type of macro.
+ (_gl_TS_var_match): Simplify regexp.
