R devel - Feb 2013 - How to NAMESPACE OS-specific importFrom?

I'd like to importFrom(parallel, mccollect, mcparallel) but on Windows these
are
not exported because this

if(tools:::.OStype() == "unix") {
     export(mccollect, mcparallel, mc.reset.stream, mcaffinity)
}

appears at src/library/parallel/NAMESPACE:6 of svn r61857. So should I be doing

if (tools:::.OStype() == "unix") {
     importFrom(parallel, mccollect, mcparallel)
}

in my NAMESPACE? I have a recollection that this has come up before, perhaps 
even in the parallel package, but I'm not able to find anything.

Thanks,

Martin Morgan

Yes.

Those are low-level functions in 'parallel': we provide stubs on Windows
for user-level functions (which is where it came up before these were 
added).
