Tough call. I seriously don't have a full answer to this.
The "right" thing is not to add global variables. If you
need to cache it depends on the cost it has to compute that
info. If it is potentially expensive, we nowadays have the
memcache (see include/memcache.h) as a place where you can
store this kind of info. If it's relatively cheap or called
infrequently, then compute it on demand.

I know that lib/version.c does not really fit into that
argument, I just did not have the time yet to see whether it
would be worth removing the global in version.c.

Another question that came up on irc this morning: Do you
happen to know whether you can pass arbitrary IOCTL calls
from the NT user space to a CIFS server? At one point I have
tried that, but at least from a Win32 app only very few
special IOCTLs were allowed.
