Probably so, but I can't imagine any C compiler choosing a representation
other than two consecutive floats, because Fortran requires that a
COMPLEX must take up the same space as two REALs.  Nobody is going to
implement complex numbers in C in a way that's incompatible with Fortran
(other than C being row-major rather than column-major).
