exponential integral as solution of ode?



Hello,

I saw some posts about the exponential integral being implemented.

I am working on a problem now where the exponential integral is the 
solution of an ode. 

A simple ode that gives Ei as a solution is
de : diff(y(x),x) = y(x)*exp(1/x);
Maple solution:
y(x) = _C1 exp( x exp(1/x) + Ei(1, - 1/x) )  


Will it be possible to get the solution of this ode in terms of exponential 
integrals (during or after the call to ode2)?
