I've now self-compiled cygwin dll on a third system and can run a cygwin 
console.
But the build process did not generate the cygwin-console-helper, maybe 
that's the reason why mintty does not start?

In the cygwin console, it does not, echos the cursor-up escape sequence 
instead. See my previous comment that I think ConPTY should only be 
applied if running at a pty. (And for other reasons only when starting a 
non-cygwin app.)
