Line 35:
* As the recommended thing to do, it puts everyone following the recommended practice on similar footing. No comparing of (vanilla) gcc-4.5.2 with (Gentoo) gcc-4.5.2-r1 or (Ubuntu) gcc-4.5.2-1ubuntu3 or (Cygwin) gcc4-4.5.2-2 or somesuch.

For the record, I completely agree with Love4Boobies and completely disagree with Solar. Building a crosscompile toolchain for later work is solely useful to cut down on the extra arguments needed to be given. You can achieve the same result with -ffreestanding -nostdlib -nostdlibinc (for the kernel) and --sysroot for usermode apps.
Not to mention that recompiling the compiler is a GCC-ism. Clang doesn't require it, it is naturally a crosscompiler, in which case you use --sysroot as well (until someone fixes the compiler driver to support dynamic retargetting, which is on my agenda but hasn't been done yet) -- JamesM
