xkbstr.h uses types from Xdefs.h (eg. Bool) but doesn't include it.
If somebody includes it, w/o including Xdefs.h first, compile breaks:
../include/xkbstr.h:84:5: error: unknown type name ‘Bool’
84 | Bool active;
| ^~~~
../include/xkbstr.h:517:5: error: unknown type name ‘Bool’
517 | Bool num_groups_changed;
| ^~~~
../include/xkbstr.h:608:5: error: unknown type name ‘Bool’
608 | Bool has_own_state;
| ^~~~
