Hi there guys can someone please tell me what this means.
 
2 C:\Dev-Cpp\include\c++\backward\backward_warning.h:32
#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.
