+- Return type of wxString::c_str() is now a helper wxCStrData struct and not

+  and "const wchar_t *", so this only presents a problem if the compiler cannot
+  apply the conversion. This can happen in 2 cases:
+
+  + There is an ambiguity because the function being called is overloaded to
+    take both "const char *" and "const wchar_t *" as the compiler can't choose
+    between them. In this case you may use s.wx_str() to call the function
+    matching the current build (Unicode or not) or s.mb_str() or s.wc_str() to
+    explicitly select narrow or wide version of it.
+
+    Notice that such functions are normally not very common but unfortunately
+    Microsoft decided to extend their STL with standard-incompatible overloads
+    of some functions accepting "const wchar_t *" so you may need to replace
+    some occurrences of c_str() with wx_str() when using MSVC 8 or later.
