[commit] Fortran complex number test

[Daniel Jacobowitz <drow at false dot org>]

Ages ago (November 2001) we got a report that printing complex numbers
from a Fortran program did not work.  Nowadays it works fine; I
suspect stabs or an old GCC were to blame.  Still, it seems like a
sensible thing to test; so I checked in this test, which passes on
x86_64-linux (using either g77 or gfortran).
