+   This option can enable complex type support in libgccjit. By default,
+   no complex types can be used.
+
+   If you use complex types, it is recommended to use builtin functions
+   `creal`, `cimag` and `conj` etc. with the correct type suffix, since
+   those are inlined into the code, rather then imported functions from
+   the math lib which are not. See :ref:`gcc_jit_context_get_builtin_function`.
+
+   This entrypoint was added in :ref:`LIBGCCJIT_ABI_16`; you can test for
+   its presence using
