Re: #include <cstddef> may declare size_t only in namespace std

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

The message I posted in July was wrong. gcc 4.7, like previous versions 
of gcc, declare much more in the global namespace than required by the 
C++ standard. See https://bugzilla.gnome.org/show_bug.cgi?id=681071#c3.

Even though it's not required by gcc 4.7, I have change size_t and 
ptrdiff_t to std::size_t and std::ptrdiff_t in gtkmm, glibmm and libsigc++.
