The GCC user manual shows a -fno-rtti compiler switch. To me, this
implies that is is normally enabled. The opposite switch, of course, is
-frtti. If it has to be built into the compiler then check to see what
configuration switches are available before making the compiler.

So I suggest looking through the available documentation, as I'm not
familiar with this.
