Yes you are right, but gcc-4.9 does not find gnat1:
make[3]: Entering directory '/home/srs/DEBs/gnat-4.9/music123-16.3'
gnatmake -j1 -R -v -eS music123 -cargs -g -O2 -fstack-protector-strong
-largs -Wl,-z,relro -Wl,--as-needed -Wl,-z,defs

  "music123.ali" being checked ...
  -> "music123.ali" missing.

gcc-4.9: error trying to exec 'gnat1': execvp: No such file or directory
End of compilation
gnatmake: "music123.adb" compilation error

and it is here:
dpkg -S /usr/lib/gcc/i486-gnu/4.9/gnat1
gnat-4.9: /usr/lib/gcc/i486-gnu/4.9/gnat1

(can it be something in the gnat package?)
