The compiler is unhappy that one of the parameters in a call to sprintf is also the buffer it's supposed to output to, when that parameter is marked "restrict", which means it shouldn't alias to other arguments. Also, this code can't go inside the gem5 namespace, since it has a main() function in it. The linker will look for main(), not gem5::main().
