* Propose using $(STDCPPLIBS) definition for version-independent linking

of standard C++ libraries (stdc++.r4 <-> stdc++ supc++);
* Force C++ language at preprocessing the sources before localization catkeys
  collecting. It gives a hint for compiler to handle .pre file as C++ one 
  preventing breaking on "unfound" C++ headers. Thanks to Vitaly Diger for 
  pointing it out.
