Octave-2.1.35 and Cygwin-1.3.5

[Topas]

I use the oct-rl-edit.cc in the CVS,
and built the Octave-2.1.35 successfully under Cygwin-1.3.5

But, when I run a test program

#! /usr/local/bin/octave -qf
gnuplot_binary="pipe-gnuplot wgnuplot"
putenv("TMPDIR",".");
a=rand(10000,1);
subplot(3,1,1);
plot(a);
b=autocor(a,256);
subplot(3,1,2);
plot(b);
subplot(3,1,3);
plot(abs(fft(b)));
printf("\n");
printf("You can see 3 plots\n");
printf("(1) 10000 points random signal\n");
printf("(2) autocorrelation function of (1)\n");
printf("(3) power spectral density of (1)\n");
printf(" ENTER RETURN TO EXIT\n");
pause;

Some ERROR message appeared, the above prgram worked fine before
The error message is

gnuplot_binary = pipe-gnuplot wgnuplot
error: `center' undefined near line 38 column 7
error: evaluating index expression near line 38, column 7
error: evaluating assignment expression near line 38, column 5
error: called from `autocov' in file 
`/usr/local/share/octave/2.1.35/m/signal/autocov.m'
error: called from `autocor' in file 
`/usr/local/share/octave/2.1.35/m/signal/autocor.m'

It seems like the problems of environment variable? (I don't sure)
I just wonder if anyone using Octave-2.1.35 under Cygwin-1.3.5 ?
