Does not happen for me. Maybe you are compiling without –O (odd, but possible)? mapMaybeFB is mentioned only inside a RULE, so perhaps it’s regarded as un-referenced without –O?

Subject: Getting error about unused instances during "sh validate"
am I the only one to get the following when I run "sh validate"?
Defined but not used: ‘mapMaybeFB’
<no location info>:
Failing due to -Werror.
make: *** [libraries/base/dist-install/doc/html/base/base.haddock] Error 1
make: *** Waiting for unfinished jobs....
make: *** [all] Error 2
I'm working on this ticket, but I can't see how that can be related:
