+ 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.
