I think this is actually legitimate a build error (see e.g. https://dev.azure.com/gitgitgadget/git/_build/results?buildId=2394), and I am quite surprised that GCC accepts this. Note: after thinking about this for a while, I guess an empty string would work, too (i.e. "" instead of " 0"), but I already waited for the macOS build to finish at https://github.com/gitgitgadget/git/pull/139, and it's a fixup! for Jonathan to pick up, anyway... Junio, could I ask you to apply this on top of your SQUASH??? to fix the build?
