[Rd] odesolve dynload example

[Setzer.Woodrow at epamail.epa.gov]

I'm the maintainer of odesolve.  In the ...odesolve/dynload/c directory
of the windows distribution are two files that should not be: mymod.o
and mymod.so (I just noticed them).  Try deleting  them and rerunning
your compilation.

By the way, you might want to take a look at deSolve, which supercedes
odesolve.  deSolve includes lsoda with the same API as in odesolve, but
also includes several other ode solvers you might find useful.  In the
next several months, odesolve will be deprecated.

I'm a bit rusty on the windows tools, but it looks like mymod.o and
mymod_res.rc  not being made above. Any chance that you have old
versions lying around?
