22 file because the details of swapping depend on the details of the
23 structures used by each COFF implementation. This is included by
24 coffcode.h, as well as by the ECOFF backend.

26 Any file which uses this must first include "coff/internal.h" and
27 "coff/CPU.h". The functions will then be correct for that CPU. */
