programmering i Linux

Jeg har lavet mit første program i Linux, og kompillerer det:

g++ lst01-01.cpp -o hello
In file included from /usr/include/g++/backward/iostream.h:31,
                from lst01-01.cpp:1:
/usr/include/g++/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.


Hvor finder jeg den omtalte dokumentation??? Kap. 17 osv.
