problems.

Hello Ray,

thank you for your report. I will have a look at the numerical accuracy of the
functions.

Betreff: [Maxima] Testsuite failures

I'm getting the following failures in the testsuite:

********************** Problem 303 ***************
Input:
integrate(bessel_y(11, x), x)

Result:
error-catch

I think this due to a typo in the integral formula for bessel_y.
There's a call to simplify with two args instead of one.  I think the
second arg should be removed, or simplify should by simplifya.

Clisp (2.47) fails rtest_gamma:

I guess the tolerance needs to be increased a bit.  The CMUCL failures
may indicate an issue with some CMUCL routines since CMUCL fails more
tests than the other lisps.
