(David's words, not mine) I vehemently disagree with the deprecation of ARCH=i386 and ARCH=x86_64 and with the characterisation as well. > [...] but I regularly type "make ARCH=i386" when building 32-bit > kernels on a 64-bit system, and my scripts use "make ARCH=x86_64" > when building 64-bit kernels (just in case I happen to have booted > a 32-bit kernel). Ditto here. They are not just useful but logical as well. This is what the whole thread is about: i want this behavior to be *preserved*.
