Hi,
On my personal machine everything works fine, but our CI build
machine suffers from this error:
```
clang-cl.exe: warning: unknown argument ignored in clang-cl '-
target' (did you mean '--target='?) [-Wunknown-argument]
clang-cl.exe: error: no such file or directory:
'x86_64-pc-windows-msvc'
```
I have the impression that options are given as the Microsoft
preprocessor expects them, but that the clang preprocessor is
called instead. I think that on my personal machine the
Microsoft preprocessor is called, which is also what I would
expect, but I don't know of a way to verify that; the workings
of ImportC are rather opaque.
ldc and dmd have differing behaviors.

And yes it prefers clang-cl.
Which means this is a bug.
It could be a bug, but locally I use the same version (ldc
1.39.0) and it works fine... Thanks for pointing to the driver
source, maybe I can work out what it is doing.
