gcc/cc treats the source code as C, where that syntax involving cout
means something (very) different (left-shift).  g++/c++ treats the
source code as C++ where operator overloading on the cout object (an
ostream) makes the left-shift operation mean something completely
different (equivalent to a function call, like write).

The link error is related to the default libraries that are linked in,
for gcc/cc it's just libc (and maybe some others).  For g++/c++ it should
include libstdc++ (which is where cout and other things live).
