[computer-go] C++: sstreams

[Santi Ontañón]

even that won't work, in C/C++ you cannot compare strings directly  
(string is not a base type in C, so it does not have an == operator,  
if you use it, basically you are simply comparing the pointers), you  
need to use strcmp, so it'll be

assert(strcmp(s.str(),"...")==0);
