+/* _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

+ (Closes: #1660)
+
+The problem is that check_pgsql validates the Database name and has different assumptions
+that postgres itself.
+
+I fail to see a reason to validate the database name here. Postgres'es API should
+do this - So i would suggest a fix like this by removing is_pg_dbname alltogether.

+Fix parsing of the long options --help and --version. The special
+handling must be done before calling getopt().
+This fixes erroneous output like:
+
+    ./check_icmp --version
+    ./check_icmp: invalid option -- '-'
+    ./check_icmp: invalid option -- 'e'
+    ./check_icmp: invalid option -- 'r'

+check_curl fails on large pages:
+
+  HTTP CRITICAL - Invalid HTTP response received from host on port 5080: cURL returned 23 - Failure writing output to destination
+
+for example trying to run check_curl on the test from #1822
+
+I guess the idea is to double the buffer size each time it is to small. But the code
+exponentially grows the buffer size which works well 2-3 times, but then fails.

+    # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by

+    #      UTF-8. In a canonical UTF-8 Unicode string, all decomposable
+    #      characters are decomposed ..."

-
-   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

-          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>
