| 611 this is a warning hack. The idea is to use this everywhere that we | |
| 612 get the "discarding const" warning from gcc. That doesn't actually | |
| 613 fix the problem of course, but it means that when we do get to | |
| 614 cleaning them up we can do it by searching the code for | |
| 615 discard_const. | |
| 616 | |
| 617 It also means that other error types aren't as swamped by the noise | |
| 618 of hundreds of const warnings, so we are more likely to notice when | |
| 619 we get new errors. | |
| 620 | |
| 621 Please only add more uses of this macro when you find it | |
| 622 _really_ hard to fix const warnings. Our aim is to eventually use | |
| 623 this function in only a very few places. | |
| 624 | |

| 626 makes the return type safe. | |
