Hi All,
I'm ensuring that the Spack packager can build m4 on OS X High Sierra.
Here's my PR for them:
https://github.com/spack/spack/pull/8559
It's a repackaging of a patch from the Homebrew project's m4 recipe, here:
https://github.com/Homebrew/homebrew-core/blob/master/Formula/m4.rb#L18-L25
I'm not sure if the issue was reported to you or not, so I am.
Thanks,
g.
