Luke Leighton f40427291e added a dummy function (space in front so make proto doesn't pick it up)
to call the unused static functions in pipes.c.  avoids need to move
#if UNDEFINED_NTDOMAIN about, to stop compiler warnings while code is
being developed, but might be released as-is.

make much sense, but will do *something*. The real reason for this
support is to be able to do transactions on them (well, on lsarpc
for domain login purposes...).
