<a name="index-Complex-function"></a>
<p>Some Fortran compilers, including <code>g77</code>, let the user declare
complex functions with the syntax <code>COMPLEX FUNCTION name*16()</code>, as
well as <code>COMPLEX*16 FUNCTION name()</code>. Both are non-standard, legacy
extensions. <code>gfortran</code> accepts the latter form, which is more
common, but not the former.
