-@chapter C++ Implementation-Defined Behavior
-@cindex implementation-defined behavior, C++ language
-
-A conforming implementation of ISO C++ is required to document its
-choice of behavior in each of the areas that are designated
-``implementation defined''.  The following lists all such areas,
-along with the section numbers from the ISO/IEC 14882:1998 and ISO/IEC
-14882:2003 standards.  Some areas are only implementation-defined in
-one version of the standard.
-
-Some choices depend on the externally determined ABI for the platform
-(including standard character encodings) which GCC follows; these are
-listed as ``determined by ABI'' below.  @xref{Compatibility, , Binary
-Compatibility}, and @uref{https://gcc.gnu.org/readings.html}.  Some
-choices are documented in the preprocessor manual.
-@xref{Implementation-defined behavior, , Implementation-defined
-behavior, cpp, The C Preprocessor}.  Some choices are documented in
-the corresponding document for the C language.  @xref{C
-Implementation}.  Some choices are made by the library and operating
-system (or other environment when compiling for a freestanding
-environment); refer to their documentation for details.

-@cite{Whether an argument of class type with a non-trivial copy
-constructor or destructor can be passed to ... (C++0x 5.2.2).}

-Such argument passing is supported, using the same

-arguments of such types.
