I'm sending a copy of this to the ECL list, since I can't see what's
going wrong from here, nor can I get ecl to build on my system. The
background is that Marko is trying to use Ltk with ECL under windows,
but it looks like something fails very early on. The wish subprocess
starts up, but when sending its initialization commands to Tcl, he
gets this less-than-explicit error.

ECL guys: are the backtraces more usable when loaded from source or
from compiled files?

That's not the most helpful backtrace I've ever seen, but it looks
like something in send-wish is causing this "Invalid argument" error?
