C++ Compilers
http://www.borland.com/downloads/download_cbuilder.html borland is a lot better than dev, dev is just an IDE, far less powerful
http://gcc.gnu.org/ for linux is good
EDIT: here is a good list of a lot of compilers http://www.compilers.net/Dir/Free/Compilers/CCpp.htm
When it comes to Windows development, nothing beats Visual Studio as an IDE. I do prefer the gcc compiler, but for an IDE/Debugger, use Visual Studio. Buy a legitimate copy, no piracy here kthx.
If you're thinking cross-platform, specifically using Qt or ACE, go for Bloodshed Dev. If you're just using Windows, use VS.
