/**
|
|
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.
