Using glibc headers with ImportC

[qua via Digitalmars-d-learn]

I'm trying to get D to use my system's libc. First of all, is 
such a thing possible with importc? Walter Bright's slides on 
importc say it should be "as easy as import stdio;", but it 
doesn't seem to be the case yet. In the specification page I see 
that importc looks for .c and .i files, not .h . Is it possible 
to do what I'm trying to do? And if so, how?

By the way, I know I can "import core.stdc.stdio;" and I'm sure 
it's a better option. I'm not trying to do anything important 
here, it's just to figure out how it works.
