Note 1: This feature is supported in GCC 7.1 and 7.2 but before GCC 7.3 the

header is included without using <code class="option">-std</code> to enable C++17 support.

Note 2: This feature is supported in older releases but the

Note 3: The mathematical special functions are enabled in C++17 mode from
GCC 7.1 onwards. For GCC 6.x or for C++11/C++14 define
<code class="code">__STDCPP_WANT_MATH_SPEC_FUNCS__</code> to a non-zero value

This table is based on the table of contents of ISO/IEC FDIS 29124
Doc No: N3060 Date: 2010-03-06
Extensions to the C++ Library to support mathematical special functions
</p><p>
Complete support for IS 29124 is in GCC 6.1 and later releases, when using
at least C++11 (for older releases or C++98/C++03 use TR1 instead).
For C++11 and C++14 the additions to the library are not declared by their
respective headers unless <code class="code">__STDCPP_WANT_MATH_SPEC_FUNCS__</code>
is defined as a macro that expands to a non-zero integer constant.
For C++17 the special functions are always declared (since GCC 7.1).
</p><p>
When the special functions are declared the macro
<code class="code">__STDCPP_MATH_SPEC_FUNCS__</code> is defined to <code class="code">201003L</code>.
</p><p>
In addition to the special functions defined in IS 29124, for
non-strict modes (i.e. <code class="code">-std=gnu++NN</code> modes) the
hypergeometric functions and confluent hypergeometric functions
from TR1 are also provided, defined in namespace
<code class="code">__gnu_cxx</code>.
