This file is part of GDB.
the most brain-dead adaptation of a file format to byte order.
This module can read all four of the known byte-order combinations,
- on any type of host. However, it does make (and check) the assumption
- that the external form of a symbol table structure (on disk)
- occupies the same number of bytes as the internal form (in a struct).
- Fixing this is possible but requires larger structural changes. */
