No it's not used by default.

C++ compiler silently defaults to -fpedantic-errors unless one (or both) 
of -fpedantic or -fpermissive is specified. It's in gcc/cp/decl.c 
(procedure init_decl_processing()):

  if (! flag_permissive && ! pedantic)
    flag_pedantic_errors = 1;

Non zero value of flag_fpedantic_errors tells compiler to generate 
errors on violations of standard.
