+// Recommended setting: 1 if you use the standard streams anyhow and so

+// Currently the Digital Mars and Watcom compilers come without standard C++
+// library headers by default, wxUSE_STD_STRING can be set to 1 if you do have
+// them (e.g. from STLPort).

+// VC++ 5.0 does include standard C++ library header, however they produce
+// many warnings that can't be turned off when compiled at warning level 4.
