Hello Ray,
these are my results with GCL 2.6.8 for the test failures you have reported in
rtesthyp.mac.
At the moment I have no idea what is going on. I do not see if these tests
depend on changed code concerning the gamma_incomplete funtion.
Could you please mail your results?

Betreff: [Maxima] Test suite failures with cvs version?
Anyone notice that there are now test failures with the cvs code with
gcl and ecl? The test suite works fine with clisp and cmucl.
With gcl, I am now getting failures for rtesthyp.mac for the tests 85,
86, 88, and 90. The results are supposed to be zero, but they're not.
With ecl, rtest_gamma test 304 fails. Looks like a round-off issue.
I think the desired rel error is 5e-15, but the result is
5.843059089895418419617834798317313b-15.
rtest_expintegral tests 153, 159, and 161 all give error-catch results
instead of an empty list.
Ray
