--- Comment #8 from Rafał Mużyło galtgendo@o2.pl --- Maybe rather than a bug, it's simply something Windows doesn't do ?
LC_MONETARY n_sign_posn with a value 0 gives parentheses, values 1/3 give preceding minus. There's a chance Windows (or at least this program) doesn't apply this value or they differ between Windows and Linux.
