+ * on negative results from the isl function.
+ *
+ * Static methods call "method" by passing all arguments to the underlying isl
+ * function, as no this-pointer is available. The result is a newly managed
+ * isl C++ object.
+ *
+ * Constructors create a new object from a given set of input parameters. They
+ * do not return a value, but instead update the pointer stored inside the
+ * newly created object.
+ *
+ * If the method has a callback argument, we reduce the number of parameters
+ * that are exposed by one to hide the user pointer from the interface. On
+ * the C++ side no user pointer is needed, as arguments can be forwarded
+ * as part of the std::function argument which specifies the callback function.
+ *
+ * Unless checked C++ bindings are being generated,
+ * the inputs of the method are first checked for being valid isl objects and
+ * a copy of the associated isl::ctx is saved (if needed).
+ * If any failure occurs, either during the check for the inputs or

+#
+# SYNOPSIS
+#
+#   AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the specified
+#   version of the C++ standard.  If necessary, add switches to CXX and
+#   CXXCPP to enable support.  VERSION may be '11' (for the C++11 standard)
+#   or '14' (for the C++14 standard).
+#
+#   The second argument, if specified, indicates whether you insist on an
+#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+#   -std=c++11).  If neither is specified, you get whatever works, with
+#   preference for an extended mode.
+#
+#   The third argument, if specified 'mandatory' or if left unspecified,
+#   indicates that baseline support for the specified C++ standard is
+#   required and that the macro should error out if no mode with that
+#   support is found.  If specified 'optional', then configuration proceeds
+#   regardless, after defining HAVE_CXX${VERSION} if and only if a
+#   supporting mode is found.

+#   AX_CXX_COMPILE_STDCXX_11([ext|noext], [mandatory|optional])
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the C++11
+#   standard; if necessary, add switches to CXX and CXXCPP to enable
+#   support.
+#
+#   This macro is a convenience alias for calling the AX_CXX_COMPILE_STDCXX
+#   macro with the version set to C++11.  The two optional arguments are
+#   forwarded literally as the second and third argument respectively.
+#   Please see the documentation for the AX_CXX_COMPILE_STDCXX macro for
+#   more information.  If you want to use this macro, you also need to
+#   download the ax_cxx_compile_stdcxx.m4 file.
