2.1.57 : error: can't rename read-only function

[Fredrik Lingvall]

I get the following error msg when doing an fft,

octave:1> x=fft(randn(100,1));
error: can't rename read-only function `fft'
error: unable to rename `fft' to `builtin#fft'
error: unable to rename `dispatch#fft' to `fft'

and this is the output of whos,

octave:2> whos

I'm using 2.1.57 and ocatave-forge (CVS from 2004.04.11).

Octave is compiled with (gcc 3.2.2 20030222  - Red Hat Linux 3.2.2-5) :

export CXXFLAGS='-O3 -fomit-frame-pointer -funroll-loops 
-fprefetch-loop-arrays -march=pentium4 -mfpmath=sse -msse2 -pthread'

./configure --with-blas=blas_goto_p4_512 --with-lapack=lapack_LINUX_p4 
--enable-shared --enable-dl

Anyone have an idea what is causing it?

Fredrik
