Testing this PR locally
If you don't have a local development environment setup, you can use Digger to test this PR:
dub run digger -- build "master + tools#455"
Ideally we would use something like escapeShellCommand so that the output is still unambiguous (and can be copy-pasted into a shell to maybe reproduce the problem).
But... why is gcc being run with DMD's parameters? Why is there a backslash? This raises questions.
Haha, I'm forking rdmd to build a rgcc to quickly run gcc or clang on my Windows.
Yes, this is what I want: When I'm not familiar with rdmd/rgcc's own options (especially as a D beginner), there's a chance I want to check and directly copy the Failed output what rdmd/rgcc internally does, and try to run it quickly to know what is wrong.
