Otherwise it would not even begin to work fro cross compilers. Note that I'm talking about ada/rts, which gets installed under adainclude and adalib, and used by Ada apps. That's the target run-time. Maybe you are talking about the part of the Ada run-time which is used by the compiler itself, in which case, it's considered as a source of the compiler, and treated as such (built successively by all compilers from bootstrap compiler to stage2 compiler).
