At this point, gnatmake should call gcc-4.9 -c hello.adb (since
hello.adb has changed on disk) but it doesn't in your case. For me this
worked and I tried both gnat-4.9 4.9.1-1 and 4.9.1-3.

I suggest you "rm -f b~* *.o .ali" and call gnatmake again. I presume
there was an error wherein some file was modified in an editor but not
on disk?
Anyway, I can only say: "works for me"...
