Patch 8.1.1320
Problem: It is not possible to track changes to a buffer.
Solution: Add listener_add() and listener_remove(). No docs or tests yet.
Files: src/structs.h, src/change.c, src/proto/change.pro
After this patch I get this linker error from mingw64 (gcc 9.1.1):

It seems we have a mismatch of FEAT_* symbols.
In change.c, get_callback() is called from f_listener_add().
free_callback() is called from f_listener_add() and f_listener_remove().
These two f_listener*() functions are defined if FEAT_EVAL is set (line
154 to line 289).
In evalfunc.c get_callback() and free_callback() are defined if
FEAT_JOB_CHANNEL or FEAT_TIMERS or PROTO are set (line 14678 to line 14719).
Note that these line numbers are after the inclusion of patch 8.1.1321.
Cheers
John
