Well, so much for the simple and easy option, then.  Does the remote 
always have a Bourne shell?  Could you simply execute "export a=val 
b=val" first?  Or add another GCC callback that resolves what type of 
shell the remote has and produces the correct "export"/"setenv"/"set" 
command?

Overall, I agree that DejaGnu should eventually add a remote_setenv 
command or some way of specifying environment variables and I am 
planning to eventually rework the remote target handling after migrating 
DejaGnu to use Tcl namespaces for at least its own code.  That is pretty 
far down my TODO list however.
