Is there some option for generating a dummy main with gdc?
Alexandrescu's book (p 133) mentions a '--main', but that doesn't seem to work for gdc, and i can't find one from 'gdc --help'.
The --unittest option does work, although, for whatever reason, you cannot just stick 'void main( ) { }' inside a unittest { } block. (Or you can, but you won't get even a warning about conflicting symbols, so i suppose the name 'main' gets mangled somehow in this context.)
I'm using debian stretch, and thanks in advance for any clues.
