setlocale(LC_ALL, "") is the way.  Emacs does that if LC_ALL is unset or not 
"C".

However, because of internal reasons, Emacs also does:
  /* The Emacs Lisp reader needs LC_NUMERIC to be "C",
     so that numbers are read and printed properly for Emacs Lisp.  */
  setlocale (LC_NUMERIC, "C");

Can you describe in more detail the problem you are seeing?  I.e. what output 
is wrong?
