+ tests init: new function 'fatal_', for hard errors
+ Before this patch, the only way offered by tests/init.sh to
+ properly signal a hard error was the `framework_failure_'
+ function. But the error message issued by that function,
+ as its name would suggest, refers to a set-up failure in the
+ testsuite, while hard errors can obviously also be due to
+ other reasons. The best way to fix this inconsistency is to
+ introduce a new function with a more general error message.
+ * tests/init.sh (fatal_): New function.

+ test-perror2.c: avoid warning about unused variable

+
+ perror: avoid spurious test failure on HP-UX
+ * tests/test-perror.sh: Use Exit to avoid wrong exit status.
+
+ tests: fix logic bug in init.sh
+ * tests/init.sh: (gl_set_x_corrupts_stderr_): Clear for successful
+ shell.

+
+ 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.

+ idcache: Fix module description.
+ * modules/idcache (Include): Set to "idcache.h".

+
+ gnulib-tool: fix portability problem with MacOS sed
+ A sed command like "/x/{s/a/b/}" is not portable; a newline is needed
+ before the "}". Problem reported by Leo in
+ <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00717.html>.
+ * gnulib-tool (func_modules_transitive_closure): Insert newlines in
+ sed_extract_condition1, sed_extract_condition2.

+ symlinkat.

+
+ 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,
+ sometimes we must *not* use it. Adjust uses accordingly.
+ (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
+ "extern unsigned char const *" declaration in idutils.
+ (_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.
+ (_gl_TS_obj_files): New configurable variable.
+ (_gl_TS_headers): Likewise.

+
+ verify: fix bug when gnulib <assert.h> is also included
+ * lib/verify.h (verify, verify_true): Define if _GL_VERIFY_H
+ is defined, not if _GL_STATIC_ASSERT_H is not defined.
+ Perhaps there's a better way, but this fixes the immediate problem.
+ Problem reported by Bruno Haible in

+ New module 'mktime-internal'.
+ * modules/mktime-internal: New file.
+ * m4/timegm.m4 (gl_PREREQ_TIMEGM): Move contents to ...
+ * m4/mktime.m4 (gl_FUNC_MKTIME_INTERNAL): New macro. Define
+ mktime_internal as a C macro if libc has __mktime_internal.
+ * modules/timegm (Depends-on): Add mktime-internal. Remove mktime. Add
+ conditions.
+ * MODULES.html.sh (Date and time <time.h>): Add mktime-internal.
+

+
+ timegm: Correct mktime replacement statements.
+ * m4/timegm.m4 (gl_PREREQ_TIMEGM): Set REPLACE_MKTIME, instead of
+ defining mktime as a C macro. This completes a 2009-07-28 commit.
