New review comment by aurieh on void-packages repository https://github.com/void-linux/void-packages/pull/25878#discussion_r512027536 Comment: Had a shot at tracking down where `CRuntime_Musl` is defined, couldn't find it; the dmd build toolchain (the entire codebase, really) is extremely convoluted. What I *do* know is that `CRuntime_Musl` is set when building both `dmd2.091` and `dmd` (`2.094.1`), made sure using a message pragma. Not sure why properly declaring `vfork()` doesn't help, it's really strange.
