Damnit! Problem exists between keyboard and chair. Command should have 
openssl smime -verify -inform DER -in t estfile.sig -binary -CAfile 
It was the decrypting messing up the asn1-structure on Win when not 
using the
binary option (-outform DER whould have worked, too).

So the code works in Win and Linux. :) Thread closed.

Best regards Jan
