In this implementation the <literal>-std=gnu++14</literal> or
|
|
<literal>-std=c++14</literal> flag must be used to enable language
|
|
and library
|
|
features. See <link linkend="manual.intro.using.flags">dialect</link>
|
|
options. The pre-defined symbol
|
|
<constant>__cplusplus</constant> is used to check for the
|
|
presence of the required flag.
