+ open-tests: port to glibc with _FORTIFY_SOURCE and -O1
+ Problem reported by Daiki Ueno in:
+ http://lists.gnu.org/archive/html/bug-gnulib/2013-06/msg00052.html
+ * tests/test-open.h (__always_inline):
+ New macro, if not already defined.
+ (test_open): Use it.
+
+2013-12-04 Eric Blake <eblake@redhat.com>
+
+ include_next: minimize code duplication
+ * modules/include_next (Depends-on): Add absolute-header.
+ * m4/include_next.m4 (gl_NEXT_HEADERS_INTERNAL): Reuse
+ gl_ABSOLUTE_HEADER_ONE instead of open-coding it.
+
+2013-12-04 Pádraig Brady <P@draigBrady.com>
+
+ getcwd: fix compile error in configure check
+ * m4/getcwd-abort-bug.m4 (gl_FUNC_GETCWD_ABORT_BUG): Include errno.h
+

+
+ regex: suppress core dumps from detection code
+ * m4/regex.m4 (gl_REGEX): Catch the SIGABRT and convert to SIGTERM
+ to suppress core dumps that may well occur on glibc systems.
+ These core dumps might not be cleaned up automatically, or could
+ trigger some system core dump handling logic.
+
+2013-12-03 Pádraig Brady <P@draigBrady.com>
+
+ md5, sha1, sha256, sha512: support mandating use of openssl
+ * m4/gl-openssl.m4 (gl_crypto_check): Adjust the --with-openssl
+ description, to list the now 3 separate options. also don't
+ mention the default=no, since this is implicit given the option
+ is described as --with-openssl rather than --without-openssl.
+ If projects change the default they're free to document that.
+ with --with-openssl[=yes] we now error out when the specified
+ hash algorithm is not available in libcrypto.

+
+ test-xvasprintf: (trivial) fix to disable some -Wformat-security diags
+ * tests/test-xvasprintf.c: Disable -Wformat-zero-length and
+ -Wformat-nonliteral checks, as these edge cases are part of the test.

+
+ regex: avoid glibc deadlock during configure
+ * m4/regex.m4 (gl_REGEX): Avoid recursive malloc deadlock when
+ glibc bug 15078 in turn triggers bug 16159.
+ Reported by Michal Privoznik.
+
+2013-12-02 Pádraig Brady <P@draigBrady.com>
+
+ md5, sha1, sha256, sha512: use openssl routines if available.
+ --with-openssl the libcrypto md5, sha1, sha224, sha256, sha384, sha256
+ routines will be used if available, requiring apps to link @LIB_CRYPTO@
+ * lib/gl_openssl.h: Provide wrappers for specified openssl hash.
+ * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): New function to lookup libcrypto
+ in the standard system location.
+ * m4/sha1.m4: Call gl_CRYPTO_CHECK() for SHA1.
+ * m4/sha256.m4: Likewise with SHA256.
+ * m4/sha512.m4: Likewise with SHA512.
+ * m4/md5.m4: Likewise with MD5.
+ * m4/gc.m4: Ensure @LIB_CRYPTO@ set for tests.
+ * lib/sha1.h: Include wrappers if HAVE_OPENSSL_SHA1.

+ * lib/sha512.h: Likewise with SHA512.
+ * lib/md5.h: Likewise with MD5.

+ base64: (trivial) fix compilation regression on some compilers
+ * lib/base64.c: Don't return the void function,
+ instead split to a separate return statement.
+
+2013-11-28 Paul Eggert <eggert@cs.ucla.edu>
+
+ ignore-value: revert previous code change
+ * lib/ignore-value.h (ignore_value): Use __extension__ and
+ __typeof__ only for GCC 3.4 and later. Reported by Eric Blake in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-11/msg00102.html>.
+ Change the comment to try to explain this better.
+
+2013-11-27 Pádraig Brady <P@draigBrady.com>
+
+ 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().
+
+2013-11-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ 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.

+ error: depend on stdio
+ Problem reported by Nikos Mavrogiannopoulos in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2013-11/msg00084.html>
+ * modules/error (Depends-on): Add stdio.

+
+ base64: provide a fast path for encoding well sized buffers
+ Avoid conditionals in the base64 encoding loop,
+ which was seen to give 60% better throughput.
+ * lib/base64.c (base64_encode_fast): A new function to be called
+ when we don't want to NUL terminate, and we have enough space
+ in the output to encode the given input.
+ (base64_encode): Call the _fast() version when appropriate.
+ Also remove a redundant mask with 0x3F on the first encoded byte.
+
+2013-11-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ extern-inline: port better to OS X 10.9
+ * m4/extern-inline.m4: Omit serial number; this file doesn't use them.
+ (gl_EXTERN_INLINE): Do not suppress the use of extern inline on
+ OS X 10.9, except for g++ where the bug is still present.
+ See <http://trac.macports.org/ticket/41033>.

+
+ intprops: port to Oracle Studio c99
+ * lib/intprops.h (_GL_HAVE___TYPEOF__) [__SUNPRO_C && __STDC__]:
+ Define to 0, to avoid diagnostics when Oracle Studio is pedantic.
+
+2013-10-31 Paul Eggert <eggert@cs.ucla.edu>
+
+ obstack: pacify HP C
+ * lib/obstack.h (obstack_free) [!__GNUC__]: Rewrite to avoid
+ warning "conversion from pointer to smaller integer" from HP
+ C-ANSI-C - cc version B9007AA/B3910B A.06.26. It's safe to assume
+ C89 or later nowadays, so cast to void instead of int. Privately
+ reported by H.Merijn Brand. Also, change header to match glibc's,
+ to make checking against glibc easier.
+

+
+ maint.mk: prefer gpgv2 over gpgv
+ * top/maint.mk (gpgv): Use gpgv2 if present, else gpgv.
+ (gpg_key_ID): Use $(gpgv), rather than hard-coding "gpgv".
+ Reported by Gary Vaughan.
