Yes, but there is a vague area there-abouts. It seems to affect a couple of things.

Yes you need to diligently clean up after yourself, otherwise you get a kernel memory leak. But I rather did that by getting a personally managed pool of a fixed size that I can give up when I leave (that reminds me I must still program that) Its not always as easy of course.

All I found so far is what I posted before, but it might have other effects.
I suppose grepping the compiler source might bring some light.

I am not completely sure what you are up to, but it is a feat to have part with an rts and part without. I do everything without and use an include directory. But I believe I saw that one can compile with or without RTS (or with diffent RTS's I should rather say) for different packages.

But the binding the scheme seems to be regulated by the 'Suppress_Standard_Library' variable in System. So how that is going to work out in a by-morph I hate to think.

So are you trying to use that? or are you trying to drop that?
and: with or without stdlib?
