make check fails for CVS

[Todd Neal]

"make check" fails for the current CVS version.  The problem is with
dec2base.m:

Running ./octave.test/string/string.exp ...
FAIL: octave.test/string/dec2bin-3.m
FAIL: octave.test/string/dec2hex-3.m



In dec2base.m this check ignores the len argument:

92    ## Check if the first element is the zero symbol
93    if (all (retval(:,1) == symbols(1)))
94      retval = retval(:,2:end);
95    endif
