Please understand, I was not trying to argue the point.
I just had no idea that mixing libSystem with libstdc++ made a binary non-distributable.
Thank you for clarifying.

This reveals a bigger problem than just my proposal.
I do not think our buidbot recognizes this fact.
For example, the binary version of the gcc port we distribute mixes libSystem and libstdc++.

otool -L /opt/local/lib/gcc6/i386/libasan.3.dylib
	/opt/local/lib/gcc6/i386/libasan.3.dylib (compatibility version 4.0.0, current version 4.0.0)
	/opt/local/lib/gcc6/i386/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.22.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.0.0)
	/opt/local/lib/gcc6/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
