The following example has two floating point 2x2 matrices, the first of which Maxima computes the eigenvectors only after rationalizing it, and the second of which Maxima computes the eigenvectors without recourse to rat.
(%i2) A : matrix([-1.889043743820395,-0.3],[1,0]);.

The noninteractive code is not correctly following the decision tree that is thrown up by 'integrate' in the following example.
(%i1) load(noninteractive);
(%o1) "/home/work/maxima/maxima-5.19.2/share/contrib/noninteractive/noninteractive.mac"
(%i2) integrate(%e^(%i*k*x)*sin(x)/x,x,minf,inf);
(%o2) if k-1 < 0 then integrate(%e^(%i*k*x)*sin(x)/x,x,minf,inf)
elseif equal(k-1,0) then %pi...

I should add that there are two problems above: first, I and J should be equal; second, the correct answer should be
(%i19) integrate(cos(x)*sin(x)/x,x,minf,inf);
(%o19) %pi/2.

In v5.19.2, this plot command works as you wish.
I suggest upgrading your version of Maxima, since it is rather old.

The following is incorrect:
(%i2) I : 'integrate(%e^(%i*x)*sin(x)/x,x,minf,inf);
(%o2) 'integrate(%e^(%i*x)*sin(x)/x,x,minf,inf)
(%i3) J : changevar(I,y+x,y,x);
(%o3) 'integrate(%e^-(%i*y)*sin(y)/y,y,minf,inf)
(%i4) ev(I,nouns);
(%o4) %pi
(%i5) ev(J,nouns);
(%o5) 0.

The version of Maxima is incorrectly reported on the front page of the manual.

These seem infinitesimal to me at 0.5em (firefox v3.0.*). Here is a patch to make them slightly larger (0.9em).

After a few minutes of trying to make the demo web page in demo/html, I realised that webify.pl needs to be run in a shell with GNUPLOT_LIB defined. This is only apparent after reading the source. Here is a patch of webify.pl which checks if GNUPLOT_LIB is defined and non-trivial; it emits a helpful error message and halts if not.
