+Subject: [PATCH 6/6] avoid building static libs on windows when
+ BUILD_SHARED_LIBS=ON
+
+except all flags_* libraries, for which DLL builds on windows
+are not supported
+
+To do this, expand list of ABSL_INTERNAL_DLL_TARGETS; this
+is due to how the logic of absl_internal_dll_contains checks
+whether additional static libraries should be built, compare
