Thank you.
I installed Visual Studio 2022, proved the existence of cl.exe, 
and added the location to the search path.

However, there is still a problem:
```
dmd hello.c
C:\D\dmd2\windows\bin64\..\..\src\druntime\import\importc.h(134): 
fatal error C1034: sal.h: no include path set
Error: C preprocess command cl.exe failed for file hello.c, exit 
status 2

```

which looks like dmd found cl.exe, but did not supply it with all 
the data it required.
