Comment:

 This is due to a compiler warning.  In developer builds, we enable
 `-Werror` automatically to stop new warnings creeping in, so that warning
 is promoted to an error, as the `[-Werror=unused-parameter]` at the end of
 this line indicates:

 {{{
 /root/git/testing/xapian/xapian-core/api/result.h:30:7: error: unused
 parameter ‘o’ [-Werror=unused-parameter]
 }}}

 It looks like GCC 4.8.2 warns about unused parameters on `default`-ed
 methods, while GCC newer versions don't (even GCC 4.8.4 in Ubuntu trusty
 doesn't which is what our CI builds use).  I've pushed a fix in
 8417528eb9d0a6f3e00fcc97bfa33c4ae5083dae.

 This code isn't present in the 1.4 branch, so nothing to backport.

 (BTW, it's not a good idea to do software development work as root.  Only
 do things as root that require root access.)
