Problems importing core.sys.linux.epoll

[Mike Parker]

I'm experimenting with some Linux stuff right now and am currently 
working on something using epoll. But I've run into an issue where dmd 
just doesn't see anything in core.sys.linux.epoll. As a workaround, I've 
implemented my own declarations for the bits I'm using. I'm curious, 
though, if anyone else has encountered this as I've never seen anything 
like it. I get no errors at all about it not being able to find the 
module, just things like "epoll_event is undefined" and such. If I try 
something like this:

import core.sys.linux.epoll : epoll_event;

Then I get an error about the import not being found. Other modules in 
core.sys.linux import just fine.

If anyone else can verify this same issue, I'll file a bug report. 
Otherwise, any ideas on what could cause this?
