ode2 problem



I have just added a few ode2 tests.  They are taken directly
from maximabook, as we may as well check that our own examples 
work.

This one doesn't work.


Current CVS with gcl/windows

(C1) ode2( (2*x*y-exp(-2*y))*'diff(y,x)=0, y, x);


Error: .
Fast links are on: do (si::use-fast-links nil) for debugging
Error signalled by MACSYMA-TOP-LEVEL.

Not so current CVS with clisp/irix

(C1) ode2( (2*x*y-exp(-2*y))*'diff(y,x)=0, y, x);
