It seems to be somewhat transformative, this at least gets me 
different errors :).
Where does this `-unknown-linux` postfix come from? `ldc2 
-version`/`-help` did not mention it.

```
C:\Program Files\LDC 1.32\bin\..\import\core\stdc\stdio.d(1308): 
Error: function `core.stdc.stdio.vfprintf` `pragma(printf)` 
functions must be `extern(C) int vfprintf([parameters...], 
const(char)*, va_list)`
C:\Program Files\LDC 1.32\bin\..\import\core\stdc\stdio.d(1311): 
Error: function `core.stdc.stdio.__isoc99_vfscanf` 
`pragma(scanf)` functions must be `extern(C) int 
__isoc99_vfscanf([parameters...], const(char)*, va_list)`

et cetera
```

For reference, this code is purely:
```
module overig.app;
import std.stdio: writeln, readln;

int foo(int a, int b){
	return a+b;
}

void main() {
	int a = foo(1,2);
	writeln(a);
}
```
