-Subject: [PATCH] AC_HEADER_MAJOR: port to glibc 2.25
-
-glibc 2.25 is deprecating the namespace pollution of <sys/types.h>
-injecting major(), minor(), and makedev() into the compilation
-environment, with a warning that insists that users include
-<sys/sysmacros.h> instead.  However, because the expansion of
-AC_HEADER_MAJOR didn't bother checking sys/sysmacros.h until
-after probing whether sys/types.h pollutes the namespace, it was
-not defining MAJOR_IN_SYSMACROS, with the result that code
-compiled with -Werror chokes on the deprecation warnings because
-it was not including sysmacros.h.
-
-In addition to fixing autoconf (which only benefits projects
-that rebuild configure after this fix is released), we can also
-give a hint to distros on how they can populate config.site with
-a cache variable to force pre-existing configure scripts without
-the updated macro to behave sanely in the presence of glibc 2.25
-(the documentation is especially useful since that cache variable
-is no longer present in autoconf after this patch).
-
-Note that mingw lacks major/minor/makedev in any of its standard
-headers; for that platform, the behavior of this macro is unchanged
-(code using the recommended include formula will get a compile error
-when trying to use major(), whether before or after this patch); but
-for now, it is assumed that programs actually concerned with
-creating devices are not worried about portability to mingw.  If
-desired, a later patch could tighten AC_HEADER_MAJOR to fail at
-configure time if the macros are unavailable in any of the three
-system headers, but that semantic change is not worth mixing into
-this patch.
-
-* lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Drop check for
-major within sys/types.h; it interferes with the need to check
-sysmacros.h first.
-
-Signed-off-by: Eric Blake <eblake@redhat.com>

-Subject: [PATCH] perl: Replace -w option in shebangs with modern "use
- warnings"
-
-In some builds we might provide ac_cv_path_PERL as /usr/bin/env perl
-to use newer version of the perl from users PATH rather than
-older from standard system path.
-
-However using /usr/bin/env perl -w from shebang line isn't
-possible because it translates to something like
-/usr/bin/env -w perl and env complains about illegal option.
-
-To address this we can remove -w option from perl shebang
-line and add "use warnings" statement.

+Subject: [PATCH 2/7] m4sh: prefer bash over sh
 
-Some systems have /bin/sh -> dash and others /bin/sh -> bash. Bash is preferred 
-but sometimes we can sometimes end up exporting /bin/sh yet use bashisms.
+_AS_DETECT_BETTER_SHELL looks for a good shell to use, and tries to look for
+'sh' before 'bash'.  Whilst for many systems sh is a symlink to bash,
+there are many where sh is a symlink to a more minimal sh implementation.
 
-This patch puts bash first in the search results which avoids the bash/dash confusion.
+For example, Debian by default has /bin/sh -> /bin/dash: dash is a faster
+shell to start (which makes a notable difference to boot speed) but is not
+as fast as bash at executing long scripts (and configure scripts are not
+known for their conciseness).
 
-RP 2012/9/23
+Change the search order to bash then sh, so that a known-good shell (bash)
+is used if available over something which is merely POSIX compliant.
