#if defined(__BORLANDC__) && (__BORLANDC__ >= 0x550) && (__BORLANDC__ <= 0x551) && !defined(_RWSTD_COMPILE_INSTANTIATE)
//
// this is an ugly hack to work around an ugly problem:
// by default this file will produce unresolved externals during
// 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....
