codecompletion warnings under ANSI Windows

[stahta01]

I have about a dozen warnings when Compiling Code::Blocks under Windows with ANSI (Non Unicode) Build of trunk.
Does anybody care?

Edit: All dozen seem to be cause by the same line of code in the header.

Example warning below.

Code

src\plugins\codecompletion\parser\token.h|96|warning: format '%d' expects type 'int', but argument 4 has type 'long int'|

Me cares, on linux 64bit int is 32bit, long int is 64bit, so these are real errors, especially when used for non-logging purposes.

There are more (potential dangerous or at least error-prone) warnings (compiled with -Wextra):

/home/jens/codeblocks-build/codeblocks.trunk/src/plugins/codecompletion/parser/tokenizer.h:358:36: warning: comparison of unsigned expression < 0 is always false

    /** Return (peek) the previous character */
    wxChar PreviousChar() const
    {
        if ( ((m_TokenIndex - 1) < 0) || (m_BufferLen==0) ) // (m_TokenIndex - 1) >= m_BufferLen can never be true
            return 0;

        return m_Buffer.GetChar(m_TokenIndex - 1);
    };

and

/home/jens/codeblocks-build/codeblocks.trunk/src/plugins/codecompletion/parser/tokenizer.h:391:51: warning: comparison of unsigned expression >= 0 is always true

    /** Check the previous char before EOL is a backslash */
    inline bool IsBackslashBeforeEOL()
    {
        wxChar last = PreviousChar();
        // if DOS line endings, we 've hit \r and we skip to \n...
        if (last == _T('\r') && (m_TokenIndex - 2 >= 0))

There are more (potential dangerous or at least error-prone) warnings (compiled with -Wextra):

So what about:

   /** Return (peek) the previous character */
    wxChar PreviousChar() const
    {
        if ( (m_TokenIndex==0) || (m_BufferLen==0) ) // (m_TokenIndex - 1) >= m_BufferLen can never be true
            return 0;

        return m_Buffer.GetChar(m_TokenIndex - 1);
    };

and

   /** Check the previous char before EOL is a backslash */
    inline bool IsBackslashBeforeEOL()
    {
        wxChar last = PreviousChar();
        // if DOS line endings, we 've hit \r and we skip to \n...
        if (last == _T('\r') && (m_TokenIndex > 1))
            return m_Buffer.GetChar(m_TokenIndex - 2) == _T('\\');
        return last == _T('\\');
    }
