This time it took me more time, sorry about that.

I had to tweak a few flags to start CC on my host, but succeeded.

well, it's pretty target-dependent and involves some guessing and tweaks
to the cross-configuration usually. I don't know if defaults work for
your target well. Cross compilation isn't well support at this point,
but we try to improve that.

What host are you building on? ("Z:/" looks very strange if its
Linux). I doubt that the target binary would run on different operating
system at all, it must be something else imho.

I can confirm, that there is problem with ecl_min (I've tried to CC it
on my host to windows). It's certainly a bug. Please subscribe to (I've reopened
the last issue) to be kept posted.
