[Rd] Problem with WARNING...headers with CRLF line endings

[cstrato]

Dear Dirk,

Thank you for this suggestion, however I have no idea where this code 
could be used.

As I have said, this file is created automatically during the 
compilation by the compiler, and I have no idea at which point "R CMD 
check" does check for CRLF line endings, and how to interfere with this 
step. Do you have any ideas?

Best regards
Christian
