Re: [patch]: Add support of new __int128 type for targets having 128-bit integer scalar support

This trick is a bit
ugly but already in use at many places to get an signed type by
__SIZE_TYPE__ macro. As prior version worked on signed integers, I
kept here this.

I think __INTPTR_TYPE__ what you really want in these tests; I'm checking in this patch:

    	* g++.dg/cpp0x/nullptr04.C: Use __INTPTR_TYPE__.
    	* g++.dg/other/pr25632.C: Likewise.
