commit 511c2522b95333226a5e45e538fed29dd44c9be3
Author: Werner Koch <wk at gnupg.org>
Date:   Wed Jul 6 19:35:15 2016 +0200

    doc: Escape file names in generated macros.
    
    * doc/mkdefsinc.c (print_filename): New.
    (main): Use it here.
    --
    
    Our Jenkins uses an @ in directory names and thus our builds break.
