Hi Andre,

Thanks for checking out preview 2!

I don't fully understand how bits are set in cygwin. The final M3 release will 
have 'x' bit set in tar file --- just tweaked the disto roller. Is that 
enough?

We'll do something about it.

Yep, I think Dave was going to take a look.

You're right. The "import" semantics became stricter, but I classified it as 
"internal changes" and did not announce it :-)

Is the warning correct? I mean, is resource compiler run, or not? I'm not 
aware of any changes that would stop it from being run, so a test case would 
be very desirable. 

I'll try to reproduce using the part you've given, but can only try in a 3-4 
hours.

Thanks,
