00001 /* Function declarations for libiberty.
00002    Written by Cygnus Support, 1994.
00003 
00004    The libiberty library provides a number of functions which are
00005    missing on some operating systems.  We do not declare those here,
00006    to avoid conflicts with the system header files on operating
00007    systems that do support those functions.  In this file we only
00008    declare those functions which are specific to libiberty.  */
