Bug 23227 – DMD compiler can't be built without RTTI

Before the switchover from C++, it was possible to build DMD with the flags: -fno-exceptions -fno-rtti -fasynchronous-unwind-tables Since the change to D, it now only works to build with: -fno-exceptions -fasynchronous-unwind-tables Likely this is the compiler making use of certain feature that result in lowering that invoke `typeid()`. Ideally the compiler should not be doing this.

> -fno-exceptions -fno-rtti -fasynchronous-unwind-tables These are GDC flags I presume? > Likely this is the compiler making use of certain feature that result in lowering that invoke `typeid()`. Dynamic arrays and associative arrays are now being used in DMD's source code. > Ideally the compiler should not be doing this. Why not?
