Pure ANSI-C DIF FFT code

Hi

I am looking for pure ANSI-C DIF FFT code for implementing on
hardware. my implementation platform do not sup****t sin(), cos() or
trigonometric functions so I need a code with twiddle factor table or
Trigonometric function tables.
I have read Alan V. Oppenhum text book in Discrete Time signal
processing, in this book there is a dedicated chapter for computation
of FFT. are there any where that I could see implementation of these
algorithms ?
