Number lexing issue

[GoogleCodeExporter]

When we tried to get the number token, if it’s over the integer limits
2147483647(0x7fffffff)

and becomes the minor (-2147483647), we will never get the correct number.

For example,

Peek(0x8c000000,4);

The arguments pass to the peek() are

Peek(0,4);

This is because the LexGetNumber () will check the MAX_CHAR_VALUE, but does
not care the minor number

enum LexToken LexGetNumber(struct LexState *Lexer, struct Value *Value)

{

...

    if (Result <= MAX_CHAR_VALUE)

    {

        Value->Typ = &CharType;

        Value->Val->Character = Result;

        ResultToken = TokenCharacterConstant;

    }

    else

    {

        Value->Typ = &IntType;

        Value->Val->Integer = Result;

        ResultToken = TokenIntegerConstant;

    }

...

}.

What I did is as following, it might not be a good/right fix, but I am
using it now.

enum LexToken LexGetNumber(struct LexState *Lexer, struct Value *Value)

{

...

    if (Result >= 0 && Result <= MAX_CHAR_VALUE)

    {

        Value->Typ = &CharType;

        Value->Val->Character = Result;

        ResultToken = TokenCharacterConstant;

    }

    else

    {

        Value->Typ = &IntType;

        Value->Val->Integer = Result;

        ResultToken = TokenIntegerConstant;

    }

...

}.
