| 9 | * This is not a functional version of mprotect() but the SPARC backend |
---|
| 10 | * for at least gcc 2.8.1 plus gnat 3.13p and gcc 3.0.1 require it to |
---|
| 11 | * be there and return 0. |
---|
| 12 | * |
---|
| 13 | * As of gcc 4.2.2, the gcc SPARC backend doesn't appear to have a |
---|
| 14 | * way to call this for RTEMS anymore but it doesn't hurt to leave it. |
