I can reproduce this with just:

#include <vcl.h>
#include <locale>

No boost code necessary :-(

Even worse this reproduces the error as well:

#include <vcl.h>
#pragma hdrstop

enum enum_t
{
   one = 1,
   two = 2
};

int test()
{
   int a = one | two;  // error
   int b = one + two;  // error
   int c = (int)one & (int)two; // OK
   return a & b;       // OK
}

which doesn't look good at all...

Oh and the problem is present in Builder 6 as well.
