If some of the people who wrote the RTL looked at how Borland did  
things and imitated that, then yes, in principle Borland co-owns the  
copyright on parts of our RTL. There's however the EU Software  
Copyright directive which gives an exclusion in case it was for the  
sole purpose of achieving interoperability -- which is quite  
appropriate in this case.

That is true, but better safe than sorry. At least I'm not interested  
in fighting any lawsuit whatsoever, nor in having to throw away tons  
of work because we weren't careful enough.
