Re: gtkmm and C++0x

[Christopher Harvey <chris basementcode com>]

The way I understand it, when c++0x comes application developers will 
want to use it. If gtkmm doesn't support the new standard then there 
will be an odd mix of shared_ptrs and auto's for example. Is c++0x even 
backward compatible with 98? I'm not a gtkmm developer but it sounds 
like Fabien's idea below would mean writing and maintaining 2 version of 
gtkmm in the same file. I guess what I'm asking is how big a deal is it 
if gtkmm dropped c++98 support when c++0x comes out? Could we do it at 
gtkmm 3.0? Do the times line fit?
