I used the binary version. It's correct that building Qt Creator
requires Qt 4.5, Qt 4.5 libraries are included in the binary archive.

I guess because it will take some time before the future standard is
supported by all compilers and standard libraries. Though, TR1
shared_ptr from any recent GNU libstdc++ version works fine :^).

And soon QHash and QSet, with TR1 unordered_set and unordered_map. In
these cases, I prefer the TR1 counterparts, because they allow for
specifying a comparison function as a template parameter, which is
more comfortable for containers with pointers.
