FUNCTION
DESCRIPTION
These macros have the same function as their <<bfd_get_x>>
- bretheren, except that they are used for removing information
+ brethren, except that they are used for removing information
for the header records of object files. Believe it or not,
some object files keep their header records in big endian
order and their data in little endian order.

- @var{x} of 1025 returns 11.
+ @var{x} of 1025 returns 11. A @var{x} of 0 returns 0.
