[PATCH] c-pragma: adding a data field to pragma_handler

This patch is about the pragmas.

In c-family/c-pragma.h, we declare a pragma_handler which is a function 
accepting cpp_reader as parameter.

I have changed this handler in order to accept a second parameter which 
is a void *, allowing to give extra datas to the handler. I think this 
data field might be of general use: we can have condition or data at 
register time that we want to express in the handler. I guess this is a 
common way to pass data to an handler function.

I would like your opinion on this patch! Thanks!
