Having trouble compiling a C++ file? I had problems with the message:
   
"/usr/include/c++/3.2/backward/backward_warning.h:32:2: warning: #warning 
This file includes at least one deprecated or antiquated header. 
Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. 
Examples include substituting the <X> header for the <X.h> 
header for C++ includes, or <sstream> instead of the deprecated 
header <strstream.h>. To disable this warning use -Wno-deprecated."
I figured out how to fix this:
   Got rid of ".h" from C++ includes. 
   Added "using namespace std;"
