Makes total sense, I didn't realise decltype and typeof were not quite
the same thing. Attached is an updated patchset that does that.
It also includes a patch that improves unconstify and unvolatize by
using StaticAssertVariableIsOfTypeMacro instead of a custom version of
that assertion. (Like I said, in a future patch I intend to make
StaticAssertVariableIsOfTypeMacro work in C++ as well, but this seemed
like a good improvement anyway)
