Qt + (old version of) MinGW

Hi, I use the Qt SDK 1.2 with MinGW on Windows. Now, as you may know, this is an old version of MinGW (its version of gcc is 4.4.0). The reason I am mentioning this is that I use a third-party library which is built using the latest version of MinGW, and there are conflicts between that library and my application because of their use of a different version of MinGW. Now, I believe Qt uses a customised version of gcc (or something along those lines), so is that the reason they stick to that old version of MinGW? In other words, how come Qt doesn't use a more recent version of MinGW? Just wondering... Cheers, Alan.
