I think this is potentially a big deal.

If it can be made complete enough, I'd like to add support into D for it, so you 
could do things like:

     import "stdio.h";

and the D compile would fork/exec Dstep, generate the corresponding .d file, and 
import the .d file.

Some issues:

1. Passing macro definitions to Dstep

2. The name "Dstep" has no obvious relationship to what it does.

3. The -o flag is not necessary. Just "do the right thing" when you see the 
filename extension.


In fact, we could make it a general facility, where if D sees:

     import "filename.ext";

that it fork/exec's the program:

     ext_to_D filename.ext tmpfile.d

and them imports tmpfile.d.
