5.2.3 Alternate complex function syntax ¶

Some Fortran compilers, including g77, let the user declare complex functions with the syntax COMPLEX FUNCTION name*16(), as well as COMPLEX*16 FUNCTION name(). Both are nonstandard legacy extensions. gfortran accepts the latter form, which is more common, but not the former.
