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.

You're welcome and don't worry, it was inappropriately in the 'Lean' forum. ;)
You might as well just create a temporary source file with `void main() {}`, compile it once and then always link in this object when compiling the unittests, e.g., `gdc --unittest foo.d ~/main.o && ./foo`.
