can D compiler support C/C++ source code?

[donglei via Digitalmars-d]

While D is binary compatible with C code, it cannot compile C 
code nor C header files.
In order to use C/C++ binary libs， I have to convert C or C++ 
header files to D module.
It make very difficult to use C binary libs.
Can D compiler support C/C++ source code in future?
If can, it will become easy and convenient to use C/C++ libs in 
Dlang.
Hope to achieve it as soon as possible!
