19 /* The structure returned by localeconv().
21 The values for *_sep_by_space:
23 1 - if symbol and sign are adjacent, a space seperates them from the value;
24 otherwise a space seperates the symbol from the value
25 2 - if symbol and sign are adjacent, a space seperates them; otherwise a
26 space seperates the sign from the value
28 The values for *_sign_posn:
29 0 - Parentheses surround value and symbol
30 1 - sign precedes value and symbol
31 2 - sign succeeds value and symbol
32 3 - sign immediately precedes symbol
33 4 - sign immediately succeeds symbol
