- this is a warning hack. The idea is to use this everywhere that we
- get the "discarding const" warning from gcc. That doesn't actually
- fix the problem of course, but it means that when we do get to
- cleaning them up we can do it by searching the code for
- discard_const.
-
- It also means that other error types aren't as swamped by the noise
- of hundreds of const warnings, so we are more likely to notice when
- we get new errors.
-
- Please only add more uses of this macro when you find it
- _really_ hard to fix const warnings. Our aim is to eventually use
- this function in only a very few places.
-
- Also, please call this via the discard_const_p() macro interface, as that
- makes the return type safe.
