I don't know, I just remember there was a discussion about it -- probably 
on the Phobos mailing list.  Or it could be my own opinion seeping 
through, you never know. ;)

The thing is, the C stdlib is needed in druntime, therefore the headers 
need to be in druntime.  And it's pointless to have them in two places, 
therefore they should be removed from Phobos.  (std.c could arguably be 
kept for non-standard functions.)

In D1, the runtime and the standard library weren't separated, and it 
thus made sense to have the C headers in std as well.

No, and I agree they should at least be listed.
