17 /* The structure returned by localeconv().
19 The values for *_sep_by_space:
21 1 - if symbol and sign are adjacent, a space seperates them from the value;
22 otherwise a space seperates the symbol from the value
23 2 - if symbol and sign are adjacent, a space seperates them; otherwise a
24 space seperates the sign from the value
26 The values for *_sign_posn:
27 0 - Parentheses surround value and symbol
28 1 - sign precedes value and symbol
29 2 - sign succeeds value and symbol
30 3 - sign immediately precedes symbol
31 4 - sign immediately succeeds symbol
