Comment:

 This was broken in the past, fixed by
 9c685f44e873f01403fd83209487faa64aeb47fb, and then broken again by this
 commit which left a TODO to fix it:

 commit f917eeb824cfb7143dde9b12e501d4ddb0049b65
 {{{
 Author: Ian Lynagh <ian at well-typed.com>

     Add "Unregisterised" as a field in the settings file

     To explicitly choose whether you want an unregisterised build you now
     need to use the "--enable-unregisterised"/"--disable-unregisterised"
     configure flags.
