[Predef-contribute] value of __cplusplus for C++98

[massimo m. <mas...@gm...>]

 	First of all: thanks for your pre-def macro wiki. I find it very 
usefull.
 	But, about the value of __cplusplus for C++98 (ISO/IEC 
14882:1998), your value is 199707L when I find the value 199711L from 
other sources (examples: [1], [2], [3]).
 	I can say that g++ 4.7 use the 199711L value.

 	By the way, g++ pre 4.7 is incorrect and use the value 1 (see 
[2]).

 	Kind regards and sorry form my bad english.
