I downgraded my gcc version 4.6.3 to 4.3.4 but ada version is not changed gnat-4.6.3 so I got error
Ada compiler not installed on this system.
How to set my ada to gnat 4.3.4?

It depends on what system you're running on and how you installed it. You need to either install GNAT from the same build of GCC, or you need to install GNAT in such a way that it doesn't interfere with the rest of GCC.
