Ah yes, I believe tdm uses the MinGW.org runtime, so compatibility between
my mingw-w64 based toolchains and yours would not be guaranteed. Tdm does
have a GCC 4.5 release, if you want it.

I would like to upload my Qt
Builds, but they are very hard, if not impossible to get relocatable.
Perhaps someone knows of a way better than the google code project which
tried to get it right some time ago? How does Nokia make its SDK installer?
