Ok, Downloaded the new version, Used araxis File merge to compare text files and make the changes you listed from the previous version. I copied the new rent.c and rent.h into the src dir, made clean and came up with this.
reset.c: In function `reset_area':
reset.c:1471: warning: implicit declaration of function `SET_OBJ_STAT'
reset.c:1474: error: structure has no member named `create_object'
make: *** [o/reset.o] Error 1
make: *** [all] Error 2
Again cygwin on winxp.
any help is appreciated
