Description:

A glibc change added closefrom to unistd.h[1], which causes a collision with closefrom function in ulockmgr_server.c.
I attached a fix that rename the closefrom function in ulockmgr_server.c to closefrom_ to avoid the collision.
Another possible solution could be removing closefrom function from ulockmgr_server.c and using the one from unistd.h.
