The hardship I suppose is that if someone is using a version of gcc earlier 
than 3.2, instead of just installing a newer version of gcc (as you would 
with C), when upgrading the compiler she also has to recompile all her C++ 
libraries because of the C++ binary incompatibility between 3.2/3.3 (which 
are compatible with each other) and earlier version of gcc.

I suppose the issue is not what people on this list think, but on what users 
at large think.  We are probably too small a sample to reach a view.  My 
inclination would be to leave it for next time given the number of fairly 
recent distributions with gcc-2.95.  However, I do not have an objection 
which could reasonably be described as "violent", as probably not a large 
number of users of such distributions will want to install GTK+-2.4/gtkmm-2.4 
in any event.
