/* NOTE: This is a header file, but it contains executable routines.
This is done this way because these routines are substantially
on them in gdb by naming the including source file; e.g.,
'coff-mips.c':ecoff_swap_hdr_in.
- Before including this header file, one of ECOFF_32 or ECOFF_64 must
- be defined. These are checked when swapping information that
- depends upon the target size. This code works for 32 bit and 64
- bit ECOFF, but may need to be generalized in the future.

Some header file which defines the external forms of these
structures must also be included before including this header file.
