Dude, you see, it doesn't say anything about it. It says a little 
about the extension, but there is no direct answer.
This is important because C Std is very dependent on the compiler 
and its extensions, for example msvc std c does not work with 
importC. So my question is, are there any implementations of the 
standard C library that importC supports?

ImportC is not ready for general use yet. I’ve been reporting 
bugs that crop up when trying to use standard c headers, but I 
mostly use Linux and Macs so I haven’t reported any constructs it 
doesn’t understand on Windows. It’s supposed to be able to 
compile standard C11 code.

If you run into one, report it at https://issues.dlang.org and 
use the ImportC keyword!

ImportC isn't really a way to import C. It's a C compiler built into the 
D compiler. It only compiles C11 code *without* any headers (i.e. you 
can't use C standard library).

In order to properly import C headers, you have to first preprocess a C 
file (with a C preprocessor not supplied by D), and then use the output 
from that to build with your D project. And in that case, you likely 
will find it probably doesn't work yet, since it's not a ready feature.

I recommend instead just using D's hand-crafted bindings in `core.stdc` 
package, which do work.
