+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+   for FUNCTION which will then trigger a compiler warning containing
+   the text of "literal string" anywhere that function is called, if
+   supported by the compiler.  If the compiler does not support this
+   feature, the macro expands to an unused extern declaration.
+
+   This macro is useful for marking a function as a potential
+   portability trap, with the intent that "literal string" include
+   instructions on the replacement function that should be used
+   instead.  However, one of the reasons that a function is a
+   portability trap is if it has the wrong signature.  Declaring
+   FUNCTION with a different signature in C is a compilation error, so
+   this macro must use the same type as any existing declaration so
+   that programs that avoid the problematic FUNCTION do not fail to
+   compile merely because they included a header that poisoned the
+   function.  But this implies that _GL_WARN_ON_USE is only safe to
+   use if FUNCTION is known to already have a declaration.  Use of
+   this macro implies that there must not be any other macro hiding
+   the declaration of FUNCTION; but undefining FUNCTION first is part
+   of the poisoning process anyway (although for symbols that are
+   provided only via a macro, the result is a compilation error rather
+   than a warning containing "literal string").  Also note that in
+   C++, it is only safe to use if FUNCTION has no overloads.
+
+   For an example, it is possible to poison 'getline' by:
+   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
+     [getline]) in configure.ac, which potentially defines
+     HAVE_RAW_DECL_GETLINE
+   - adding this code to a header that wraps the system <stdio.h>:
+     #undef getline
+     #if HAVE_RAW_DECL_GETLINE
+     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+       "not universally present; use the gnulib module getline");
+     #endif
+
+   It is not possible to directly poison global variables.  But it is
+   possible to write a wrapper accessor function, and poison that
+   (less common usage, like &environ, will cause a compilation error
+   rather than issue the nice warning, but the end result of informing
+   the developer about their portability problem is still achieved):
+   #if HAVE_RAW_DECL_ENVIRON
+   static char ***rpl_environ (void) { return &environ; }
+   _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
+   # undef environ
+   # define environ (*rpl_environ ())
+   #endif

+Subject: [PATCH] check_mailq.pl: separate submission queue
+
+check_mailq.pl ignores the separate submission queue used in (modern?) sendmail
+implementations.
+
+For the queue output below with one message in the submission queue and no
+messages in the transport queue, check_mailq.pl reports zero messages in the
+queue because the request count from the last queue always overwrites previous
+queues. If the sendmail MTA isn't running or has become wedged, messages will
+sit in the submission queue forever.
+
+The attached patch fixes this in a backwards compatible way (i.e., it shouldn't
+break any of the currently supported formats).
+--
+Just turning attached patch of github issue #972 into a push request.
+(Closes #972)

+Subject: [PATCH 5/9] check_disk: still allow check of available disks with
+ ignore-missing param used
+
+Also add reporting of ignored paths. When paths are provided by -p and/ or -r and
+one path does not match a mounted disk, checking available disks is still
+possible. Paths provided by -p are reported as ignored, when not available. Due
+to code structure, this is not possible for -r unfortunately.

+    # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
+    #   the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
+    # - The documentation says:
+    #     "... all code that calls BSD system routines should ensure
+    #      that the const *char parameters of these routines are in UTF-8
+    #      encoding. All BSD system functions expect their string

+    #      paths, and other file-system entities must be in canonical
+    #      UTF-8. In a canonical UTF-8 Unicode string, all decomposable
+    #      characters are decomposed ..."
+    #   but this is not true: You can pass non-decomposed UTF-8 strings
+    #   to file system functions, and it is the OS which will convert
+    #   them to decomposed UTF-8 before accessing the file system.

+    #   - xterm uses ISO-8859-1 by default.
+    #   - TextEdit uses MacRoman by default.
+    # We prefer UTF-8 over decomposed UTF-8-MAC because one should
+    # minimize the use of decomposed Unicode. Unfortunately, through the

-
-   DYNARRAY_STRUCT
-      The struct tag of dynamic array to be defined.
-
-   DYNARRAY_ELEMENT
-      The type name of the element type.  Elements are copied
-      as if by memcpy, and can change address as the dynamic
-      array grows.
-
-   DYNARRAY_PREFIX
-      The prefix of the functions which are defined.
-
-   The following parameters are optional:
-
-   DYNARRAY_ELEMENT_FREE
-      DYNARRAY_ELEMENT_FREE (E) is evaluated to deallocate the
-      contents of elements. E is of type  DYNARRAY_ELEMENT *.
-
-   DYNARRAY_ELEMENT_INIT
-      DYNARRAY_ELEMENT_INIT (E) is evaluated to initialize a new
-      element.  E is of type  DYNARRAY_ELEMENT *.
-      If DYNARRAY_ELEMENT_FREE but not DYNARRAY_ELEMENT_INIT is
-      defined, new elements are automatically zero-initialized.
-      Otherwise, new elements have undefined contents.
-
-   DYNARRAY_INITIAL_SIZE
-      The size of the statically allocated array (default:
-      at least 2, more elements if they fit into 128 bytes).
-      Must be a preprocessor constant.  If DYNARRAY_INITIAL_SIZE is 0,
-      there is no statically allocated array at, and all non-empty
-      arrays are heap-allocated.
-
-   DYNARRAY_FINAL_TYPE
-      The name of the type which holds the final array.  If not
-      defined, is PREFIX##finalize not provided.  DYNARRAY_FINAL_TYPE
-      must be a struct type, with members of type DYNARRAY_ELEMENT and

-          <https://pubs.opengroup.org/onlinepubs/9699919799/functions/fgetc.html>

-            "The file-position indicator is decremented by each successful
-             call to ungetc()..."
-       2) fflush discards bytes pushed back by ungetc:
-          <https://pubs.opengroup.org/onlinepubs/9699919799/functions/fflush.html>
-            "...any characters pushed back onto the stream by ungetc()
-             or ungetwc() that have not subsequently been read from the
-             stream shall be discarded..."
-          This implies implicitly: fflush does not change the file position
-          indicator.
-       3) Effects on the file descriptor, if the file descriptor is capable of
-          seeking:
-          <https://pubs.opengroup.org/onlinepubs/9699919799/functions/fflush.html>
