ecl-16.1.2: new maxima testsuite failure

[Andrey G. Grozin]

maxima-5.37.3 built with ecl-16.0.0 runs its testsuite without unexpected 
errors. When buils with ecl-16.1.2, it fails in

Running tests in rtest8:
********************** Problem 104 ***************
Input:
ev(e5, au = 0, omega = 2)

Result:
            - u
quad_qawf(%e   , u, 0, 2, sin, epsabs = 1.0e-10, limit = 32, maxp1 = 100,
                                                                   limlst 
= 10)

This differed from the expected result:
[0.4000000000000001, 2.216570948815925e-11, 175, 0]

162/163 tests passed
