=> It seems to change the error/warning message or to add
a configure option won't be enough (for the first users want no
message, for the second they use packages).

 My only idea is to add a FreeBSD specific code which checks
if the TCP_FASTOPEN feature was enabled:
 - the service socket is opened at start up so there is no need
  to handle system configuration changes
 - sysctl should provide the required information
 - I have used FreeBSD since more than 20 years (I can
  remember 2.x versions)
 - unfortunately the new release will be published soon
  so this will be at least for the next one...

Thanks
