1 | /* Function declarations for libiberty. |
| 2 | Written by Cygnus Support, 1994. | |
| 3 | ||
| 4 | The libiberty library provides a number of functions which are | |
| 5 | missing on some operating systems. We do not declare those here, | |
| 6 | to avoid conflicts with the system header files on operating | |
| 7 | systems that do support those functions. In this file we only | |
| 8 | declare those functions which are specific to libiberty. */ | |
