C++ build failure in recent bluez headers

Hi,

is there an accepted patch for the build failure in recent Bluez
headers with C++ applications? This issue was brought up by Patrick
Ohly in the thread "bluez 4.97: build failure when used in C++ apps".
It seems to me that the patch suggested by Patrick did not receive a
final comment so far.

Currently I can't fix Syncevolution bugs for Debian because building
Syncevolution will fail due to broken Bluez headers.

Regards,
Tino
