Re: Where I download Digital Mars C Preprocessor sppn.exe?

[Marcone via Digitalmars-d-learn]

ImportC is deprecated as everything in D is deprecated and 
abandoned. No link works, every download link is broken as no one 
cares. All D code is always full of bugs and needs to be 
corrected by the user before trying to run it, in order to 
realize that it wasted time.
