Hello, Ashutosh.
I am not pro here, but recently I made the same work.
1) You have to enable FIXED_POINT flag in your defines, you are right here.
2) Regarding the isolation of SILK and CELT code: I forced the codec to use
SILK-mode only and deleted all the references to the CELT (however, inside
encoder it uses some functions even in silk-mode).
