This is causing a build failure on macOS:

gcc -m32 -c -o server/change.o server/change.c -Iserver -Iinclude -D__WINESRC__ -Wall -pipe -fno-stack-protector \
  -fno-strict-aliasing -Wdeclaration-after-statement -Wempty-body -Wignored-qualifiers -Winit-self \
  -Wno-pragma-pack -Wstrict-prototypes -Wtype-limits -Wvla -Wwrite-strings -Wpointer-arith -gdwarf-4 \
  -fno-omit-frame-pointer -O2 -g -Wno-deprecated-declarations -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0
server/change.c:236:2: error: No fd_path() function for this platform
#error No fd_path() function for this platform

The fd_path() stuff probably needs to be inside the #ifdef HAVE_SYS_INOTIFY_H block.
