Is there one specific feature though?  Here's the list of features and 
releases: https://gcc.gnu.org/projects/cxx0x.html
The thing that looks the most inconvenient to work around in 4.6 vs. 4.7 
would probably be template aliases, and even that doesn't seem too 
horrible for c++03.
Going from 4.6 to 4.5 would result in the loss of nullptr and constexpr, 
and I can see those causing a heavy burden.
If you go the other direction though, you could argue that 4.8 would be 
beneficial, as then you get access to TLS.
