glibmm 2.13, binary incompatibility

[Denis Leroy <denis poolshark org>]

So do we have a binary incompatibility between glibmm 2.12 and glibmm 
2.13 ? Somebody reported a problem here:

"2. These newer versions change the allowed parameter (at least for 
i386) for
Glib::ValueBase::init() from '(unsigned long)' to '(unsigned int)'."
