gcc vs g++ bizarre behaviour (newbie - sorry to say)

I am not having success invoking g++ via gcc. Rather than describe
it... take a look:
I tried it both with and without the -x c++ option, quoted and
unquoted. As you see g++ directly works fine. Specifics are waay down
below
bash-2.02$ ./hellocc
hello C++ GNUish world!
bash-2.02$ rm ./hellocc.exe
bash-2.02$ gcc -x "c++" hellocc.cxx -o hellocc
C:\TEMP\cccQV0Xf.o(.text+0x2a):hellocc.cc: undefined reference to `cout'
C:\TEMP\cccQV0Xf.o(.text+0x2f):hellocc.cc: undefined reference to
`ostream::oper
ator<<(char const *)'
bash-2.02$ ./hellocc
bash: ./hellocc: No such file or directory
bash-2.02$ g++ hellocc.cxx -o hellocc
bash-2.02$ ./hellocc
hello C++ GNUish world!
Thanks
Allan
