!  Description: For use with compilers that don't support move_alloc.
!  Halts with an error message.
! ============================================================================

! NOTE:  Older f90 compilers (e.g. gfortran prior to 4.2?)
! may not implement move_alloc and you will need to use this routine
! instead of resize_storage.f90 and set the
! allocation large enough in init_alloc.f90 to avoid running out of space.
