Just wanted to post here quickly before opening a GitHub issue, since I’m not sure if there is just some cleaning/resetting step that I’m forgetting…

Trying to build the `v1.0.1` tag on macOS 10.14 (Mojave), I keep running into an issue that the `libosxunwind` dependency still references `libstdc++` in its `Makefile`. Apparently, this library was deprecated in 10.13 and removed in 10.14 (in favor of `libc++`). I’ve tried a `make clean`, `make cleanall`, and `make distcleanall` to no avail.

So, is it me? Or is Julia not compiling on Mojave?

I ran into a similar problem while building Julia 0.7. It seems solved by this PR: [https://github.com/JuliaLang/julia/pull/30153](https://github.com/JuliaLang/julia/pull/30153). At the moment, you have to build Julia version 1.0 or greater to have the PR effective.
