linux kernel compliation : Is it possible to compile it by other compiler?

[freeburn]

have you ever compiled linux kernel by compilers other than gcc?


i had a argument with one my friend about "linux" vs "gnu/linux", then
this stuff suddenly came to our mind. i've always compiled linux kernel
by gcc. i know in theory any c complier with necessary "lib"s should
compile linux kernel. but is it practically possible? or have u ever
done it?
