+      # With some test programs, made for checking the internals of OpenSSL,

+      # files from within [.crypto] or [.ssl] so we can reach symbols that are
+      # otherwise unreachable (since the shareable images only exports the
+      # symbols listed in [.util]*.num), and then with the shared libraries
+      # themselves.  So we need to silence the warning about multiply defined
+      # symbols, to mimic the way linking work on Unix and Windows, and so
+      # the build isn't interrupted (MMS stops when warnings are signaled,
+      # by default), and so someone building doesn't have to worry where it
+      # isn't necessary.  If there are other warnings, however, we show them
+      # and let it break the build.
