+2012-05-26  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Merge from gnulib.  (Bug#11527)
+
+	The build procedure now creates <stdalign.h> and <sys/types.h> for
+	older hosts that lack a working <stdalign.h> or whose
+	<sys/types.h> does not define pid_t, size_t, ssize_t, mode_t.  New
+	symbols such as WINDOWS_64_BIT_OFF_T may require attention in the
+	msdos and nt builds.
+
+	Here is a precis of gnulib changes that seem relevant; please see
+	the gnulib ChangeLog for details.
+
+	2012-05-18 crypto: fix bug in large buffer handling
+	2012-05-14 ignore-value.h: remove unused _GL_ATTRIBUTE_DEPRECATED
+	2012-05-10 _Noreturn: port config.h to gcc -Wundef
+	2012-05-08 warnings.m4: give a means to specify the program to compile

+	2012-02-09 maint: replace FSF snail-mail addresses with URLs
+	2012-01-30 sys_stat: Fix support for mingw64 and MSVC.
+	2012-01-28 strtoimax: eliminate need for stdint.h, inttypes.h checks
+	2012-01-21 stdint: Add support for Android.
+	2012-01-15 Improve support for MSVC 9.
+	2012-01-08 mktime: Avoid compilation error on Solaris 11.
+	2012-01-05 Use ', not `, for quoting output.
+	2012-01-05 strtoimax: Don't replace systems where intmax_t is int.
+	2012-01-05 strtoimax: Work around AIX 5.1 bug.
+	2012-01-05 inttypes: Modernize.
+	2011-12-13 inttypes, stdint: add C++11 support
+	2011-11-26 Fix conflict between two instantiations of module 'unistd'.
+	2011-11-21 _Noreturn: Check that _MSC_VER is defined
+	2011-11-10 ptsname_r: Avoid compilation error on OSF/1 5.1.
+	2011-11-09 raise: fix mingw handling of SIGPIPE
