#57243: atom @1.30.0 fails to build on Mojave: linking against libstdc++ fails

 Keywords:  mojave       |       Port:  atom
-------------------------+--------------------
 On Mojave, the current atom port does not build. I guess the important
 section of the build log is the following:


 {{{
 :info:build clang: warning: libstdc++ is deprecated; move to libc++ with a
 minimum deployment target of OS X 10.9 [-Wdeprecated]
 :info:build ld: library not found for -lstdc++
 :info:build clang: error: linker command failed with exit code 1 (use -v
 to see invocation)
 }}}

 Full build log is attached.
