On newer versions of Octave the message is more informative:

'fft' is a built-in function from the file libinterp/corefcn/fft.cc

and you can see that file in the mercurial repository at:
http://hg.savannah.gnu.org/hgweb/octave/file/534b6f7108b7/libinterp/corefcn/fft.cc

anyway I don't think that is very interesting either, as Octave does not 
implement the fft
algorithm internally but rather relies on the FFTW library by Matteo Frigo and 
Steven G. Johnson [1] for that.
