508 dt.o, and the guts into ds[nnnn].o. Note that this is only needed for the

510 FIXME: This may no longer be necessary with grouped sections. Instead of
511 sorting on dh.o, ds[nnnn].o, dt.o, one could, for example, have dh.o use
512 .idata\$4h, have ds[nnnn].o use .idata\$4s[nnnn], and have dt.o use .idata\$4t.
513 This would have to be elaborated upon to handle multiple dll's
