error: conflicting types for 'gkrellm_fs_assign_fsusage_data'

It seems that commit 0602b3c15f3443c774ec72cd653b53d29e3b171b has
broken compilation on 32bit archs:

cc -c -Wall -O2 `pkg-config --cflags glib-2.0 gmodule-2.0 gthread-2.0`   -I.. -I../shared -DGKRELLM_SERVER -DENABLE_NLS -DLOCALEDIR=\"/usr/local/share/locale\" monitor.c -o monitor.o
monitor.c:1392:1: error: conflicting types for 'gkrellm_fs_assign_fsusage_data'
 gkrellm_fs_assign_fsusage_data(gpointer pointer,
 ^
In file included from gkrellmd-private.h:36:0,
                 from monitor.c:35:
../src/gkrellm-sysdeps.h:259:6: note: previous declaration of 'gkrellm_fs_assign_fsusage_data' was here
 void gkrellm_fs_assign_fsusage_data(gpointer fs,
      ^

Why is there gkrellm_fs_assign_fsusage_data both in src/fs.c and
server/monitor.c?
