/usr/local/include/c++/3.3.1/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.
