Hmm. If that's true, MacPorts doesn't support that yet. There isn't a supported
way for users to modify the cflags/cxxflags ports use by default. If those
flags really are necessary for software compiled on 10.15 to run on < 10.15,
then perhaps MacPorts base should add those flags to the default flags if the
deployment target is set to < 10.15 when on a 10.15+ system.
