/* Function declarations for libiberty.
|
|
Written by Cygnus Support, 1994.
|
|
|
|
The libiberty library provides a number of functions which are
|
|
missing on some operating systems. We do not declare those here,
|
|
to avoid conflicts with the system header files on operating
|
|
systems that do support those functions. In this file we only
|
|
declare those functions which are specific to libiberty. */
