The functions in question are almost-direct wrappers to shmget, shmat,
shmctl and shmdt. When support is not compiled in, they return (-1), just
as, I suppose, when you try calling shm* on a system that doesn't have
support for it.

It is all in xfree/xc/programs/Xserver/hw/xfree86/shared/libc_wrapper.c;
search for HAVE_SYSV_IPC.
