fix wrc to parse '~' and '&' in style specification

[Michael Lin]

Borland C++ compiler allows bitwise operation & and ~ to specify it's style

It was discussed before why not use xpr rule instead as it is a free 
expression, ie

style
    : xpr               { $$ = new_style($1, 0); }
    ;
However, this will render the style->and_mask useless as it is never used.
In style expression, '~' and tNOT are treated differently.
'~' is applied as it is parsed, ie from left to right like normal 
expressions,
tNOT is applied at the very end, after all other or_mask are combined.

xpr won't work here as it treats tNOT and '~' the same.

So adding '&' and '~' is a better solution here.


ChangeLog:
* get wrc to parse '&' and '~' when specifying style.
