No, a /name/ block *IS NOT* required even when the name is empty.
troutmask:sgk[218] cat a.f90 b.f90 c.f90
! a.f90
subroutine foo
common i
i = 2
end subroutine foo
! b.f90
subroutine bar
common j
j = 1
end subroutine bar
! c.f90
program c
common k
call foo
call bar
print *, k
end program c
This compiles with gfortran 4.7.0 with all of the options
you specify.

It's not required. You have a broken loader, which is not
a gfortran problem.
