This is on ia64, where kind=10 is padded to 16 bytes.
I suspect it will be the same on i686 with the same padding.
$ cat compl.f
program main
complex (kind=10) a, b
real(kind=10) rr,ri
a = (3.2_10, -2.1_10)
open (10,form="unformatted",status="replace")
write(10) a
rewind(10)
read(10) b
print *,b
rewind(10)
read(10) rr,ri
print *,rr,ri
end
$ gfortran compl.f
$ ./a.out
( 3.20000000000000 , 2.132901171296497E+2959)
