+// linking unless _RWSTD_COMPILE_INSTANTIATE is defined (Borland bug).
+// However if _RWSTD_COMPILE_INSTANTIATE is defined then we get separate
+// copies of basic_string's static data in the RTL and this DLL, this messes
+// with basic_string's memory management and results in run-time crashes,
+// Oh sweet joy of Catch 22....
