+# The following modification to CXXFLAGS is needed in the case of DragonFly
+# 4.1+ building lang/gcc5 with the gcc50 base compiler when the system
+# libraries were built by the gcc47 base compiler.  The sys.mk file
+# automatically adds -D_GLIBCXX_USE_CXX11_ABI=0 to CXXFLAGS in that case,
+# which will break the build.
