[Maxima] Exponential integrals

It seems that the commercial Macsyma is using the following notations
for the exponential integrals:
exp_int(x) for Ei(x)
sin_int(x) for Si(x)
cos_int(x) for Ci(x)
sinh_int(x) for Shi(x)
cosh_int(x) for Chi(x)
But there are some possible ambiguities with the definitions (is Ei(x)
the one of A&S or the function E1(x), Si(x) the Si function of A&S or
the si etc...).
can someone with access to the commercial macsyma compare the tabulated
values of these functions (say from A&S) with the numerical values
returned by macsyma ?
It may be better to keep Maxima definitions of special functions
close to those of the commercial Macsyma.
