[Patch] Fix libstdc++/15565

[Paolo Carlini]

Hi,

the below is what I propose to fix this rather subtle corner case.
I don't think we can do much better within the current ABI: otherwise,
perhaps, changing the __neg parameter of the __int_to_char template to
tri-state (i.e., positive, negative, and unsigned) could lead to a
cleaner solution.

I will wait until tomorrow. If everything goes well during the next
days, should be sufficiently safe for 3.4.1 too.

Paolo.
