64bit C++ compiler for Win

[kan]

hi,
suggest me a good c++ compiler for windows for compiling code for AMD64. i have heard that gcc(64bit) won't work on windows! it just works on linux? is that right?
i want c++ compiler which is compatible with ISO C++ standard.
i am planning to write OS for AMD64. And since my development environment is windows, plz suggest me good C++ compiler.

thanks.

Hmm, you could try to compile it yourself as a cross compiler - after that you at least know mostly for sure
