+# Unconditionally adding in platform version flags will result in warnings that
+# will be treated as errors by some packages. Add any missing flags here.

+# There are two things to be configured: the "platform version" (oldest
+# supported version of macos, ios, etc), and the "sdk version".
+#
+# The modern way of configuring these is to use:
+#    -platform_version $platform $platform_version $sdk_version"
+#
+# The old way is still supported, and uses flags like:
+#    -${platform}_version_min $platform_version
+#    -sdk_version $sdk_version
+#
+# If both styles are specified ld will combine them. If multiple versions are
+# specified for the same platform, ld will emit an error.
+#
+# The following adds flags for whichever properties have not already been
+# provided.
