+ * This is compile-time test for situation below not happen.
+ * STLport use many defines and auxilary structures, namespaces and templates
+ * that included via _prolog.h. After preprocessor phase we may see:
+ *
+ * extern "C" {
+ *
+ * namespace std { }
+ *
+ *
+ * This is bad, but acceptable. But in STLPORT_DEBUG mode we can see
+ *
+ * extern "C" {
+ *
+ * namespace std {
+ * namespace private {
+ *
+ * template <class _Dummy>
+ * class __stl_debug_engine {
+ *
+ * 
+ * This lead to compile-time error.
+ * [This due to sys/types.h contains
+ *
+ *  __BEGIN_DECLS
+ *  #include <bits/types.h>
+ *
+ * 
+ * i.e. include other headers within extern "C" { scope. Bad, but this is fact.]
+ *
+ * Origin of problem: STLport provide proxy-headers as for C++ headers, as for C
+ * headers. For C headers, we shouldn't expose C++ constructions, because system
+ * headers may include each other by unexpected way (from STLport point of view).
+ *
