    Current CVS seems to work. (But I didn't test on Windows.)

    Not observed in Maxima 5.9.3.99rc1 / Clisp 2.38 / Linux.
    Someone please try this on Windows. If it works OK we can
    close this report. Marking this report for followup.

    Works with maxima-5.14 on windows.

    (%i1) ode2('diff(y,x,2)-'diff(y,x)+y=cos(x),y,x);
    x/2 sqrt(3) x sqrt(3) x
    (%o1) y = %e (%k1 sin(---------) + %k2 cos(---------)) - sin(x)
    2 2

    Closing it.
    and the answer is correct, too.
