Just tried under 6.12.1 - and xmonad-contrib builds cleanly with it!
However, if I try to run hsc2hs and then ghc on this file separately -
then yes, the warning is there, together with 2 other warnins about
discarded do-notation statements that don't even exist in my source:

/usr/local/bin/ghc -Wall -c PerWindowKbdLayout.hs

PerWindowKbdLayout.hs:1:11:
    Warning: -#include is deprecated: No longer has any effect

PerWindowKbdLayout.hsc:109:4:
    Warning: A do-notation statement discarded a result of type CInt.
             Suppress this warning by saying "_ <- xkbGetState
                                                     d (256) stRecPtr",
             or by using the flag -fno-warn-unused-do-bind

PerWindowKbdLayout.hsc:126:4:
    Warning: A do-notation statement discarded a result of type Maybe
                                                                  ().
             Suppress this warning by saying "_ <- ($)
                                                     traverse update
fmap W.focus mst",
             or by using the flag -fno-warn-unused-do-bind

Which makes me think that running ghc on this file separately like
this isn't valid. If this is really important,
{-# OPTIONS_GHC -fno-warn-deprecated-flags #-} removes the #include warning.
