[bug #4068] DO uses typed selector from local instead of distant object.

------------------ Additional Follow-up Comments ----------------------------
Problem is, that DO does not seem to fetch types from remote end, or fetches 
them and uses only on one place and there are still places in -base where local 
selector info is used. 

I'm reffering to my previous email to the list:

http://mail.gnu.org/archive/html/gnustep-dev/2003-06/msg00018.html

Whole problem is described in that post.

If you would like to reproduce it, you have to get older version of StepTalk, 
because I have created a workaround for this bug.

Summary:  DO uses typed selector from local instead of distant object.

Original Submission:  Distributed Objects in -base uses information about typed 
selectors (for building method signatures and invocations) from local runtime 
instead of distant object. This is ugly behaviour and causes, for example, 
segfaults due to type mismatches or selector nonexistence.

I'm not sure about this ... DO has to handle arguments both locally and 
remotely, so the argument types on both ends of the connection must match
Where there is no type information at the local end, DO fetches it from the 
remote end, so the simple assertion that DO uses the local runtime rather than 
the remote end is not the case.  I think we need more specific 
examples/testcases of exactly what the problem is.

I seem to recall an email conversation about an objc-runtime problem with 
selector types for forwarding.  Is this the same problem in a different guise?
