# shm makes use of the ipc_perm structure defined in include/sys/ipc.h (or include/bits/ipc.h
# on some systems). That structure includes an element called key, _key or __key depending
# on the OS. Here's the variations I've been able to find with OS version numbers where
# possible.
# key: FreeBSD 6, AIX, Solaris, OS X 10.3, OS X 10.4 (conditionally)
# _key: NetBSD, OS X 10.4 (conditionally)
# __key: Debian 4 (Etch), Ubuntu 7, RH 3.3 & 3.4
# OS X side note: OS X 10.4's ipc.h (see /Developer/SDKs/MacOSX10.4u.sdk/usr/include/sys/ipc.h)
# defines structs called __ipc_perm_old (which uses key) and __ipc_perm_new (which uses _key).
# Use of __ipc_perm_new is inside this:
# #if defined(__POSIX_C_SOURCE) || defined(kernel) || defined(__LP64__)
# Obviously __ipc_perm_new is the preferred version. This code doesn't use that yet but
# will probably do so in some future version when compiled on OS X >= 10.4.
# Trying to enumerate all of the variations is a fool's errand so instead I figure it out
# on the fly using the function CountKeyUnderscores() below.
# Lots of systems use the unadorned "key" so that's the default when I'm forced to guess.
