How can I get the function and type from importC?  is there a 
auto rename mechanism ?


The most pragmatic workaround is to add a typedef to the C code:

```C
int S;
struct S { int a, b; };
typedef struct S S_t;// add this typedef
```

There's no built-in way, but you can define it yourself in a 
helper module:


```D
version(Windows)
enum os = "windows";
else version(AArch64)
enum os = "aarch64";
else
static assert(0, "unsupported os");
```

First, I will note that "windows" and "aarch64" are not in the 
same category...


Second, there are some already-built parts in phobos:

I also went ahead and did some for arch and runtime flavor, in a 
project where I needed these, feel free to steal (Boost licensed):
