+/* 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.  */
