I did a little experiment with the following code snippet:

#include <wchar.h>

typedef unsigned short JSChar;
typedef wchar_t UChar;

void foo(UChar* u)
{
}

void bar()
{
    JSChar* j;
    foo(j);
}


RVCT compiles this code without an error in C mode. However, it complains about
the type compatibility in C++ mode.

"a.cpp", line 13: Error:  #167: argument of type "JSChar *" is incompatible
with parameter of type "UChar *"
      foo(j);
          ^
a.cpp: 0 warnings, 1 error


wchar_t in C++ is not a simple typedef of short int, it is a unique type with
size of 2. So we need to typedef both JSChar and UChar to wchar_t for
compatibility.
