  # Patches:
  # 1. As of version 4.0.0, Clang fails to compile if the <iostream> header is
  #    not explicitly included. The developers are aware of this problem, see:
  #    https://www.codesynthesis.com/pipermail/xsd-users/2015-February/004522.html
  # 2. As of version 4.0.0, building fails because this makefile invokes find
  #    with action -printf, which GNU find supports but BSD find does not. There
  #    is no place to file a bug report upstream other than the xsd-users mailing
  #    list (xsd-users@codesynthesis.com). I have sent this patch there but have
  #    received no response (yet).
