Re: [Libreoffice] Updated [Patch] new BITxxx functions for ODF 1.2

Um, of course, having 64 bit integers and having the bit-wise functions work on them at full width 
is a bit different.  Easy to test though.

The Visual C++ Express Editions have had the same 64-bit (long long) support as the full-up Visual 
Studio Professional editions, etc., since the first (Visual C++ Express Edition 2005).

Visual Studio has supported 64-bit int types (long long) since at least Visual Studio 2005. See

_MSC_VER evaluates to the version of the Visual Studio compiler. See here:

                I see a lot of sal_uInt64 in the code. Is that supported for
                Windows? As far as I know at least the MSVC Express has only 4Byte
                long.

        
        Umm.. now that you mention.. sal/inc/sal/types.h has
        
        #if (_MSC_VER >= 1000)
            typedef __int64                  sal_Int64;
            typedef unsigned __int64         sal_uInt64;
        
        so what evaluates _MSC_VER to in MSVCE?
        
        Also noticing there
        
            #define SAL_CONST_UINT64(x)      x##ui64
        
        so the constant I introduced probably should use that.
        
        If MSVCE doesn't support 64bit values I might do some tricks using the
        double mantissa.
