Well, after this PR is pulled!

https://github.com/dlang/dmd/pull/14151

It's working with cpp, cl, and sppn.

Of course, the only pattern it currently detects is the simplest:

    #define XYZ 1

becomes:

    enum XYZ = 1;

Very nice, thank you Walter for all the work on importC.

It's been pulled now!

Now the major pieces of its functionality are all in place.

A big thanks to everyone who helped out with this, especially Iain!
