| /* 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. */ |
