[-- Attachment #1 --] I thought I'd sent this out, because the standard method (through "make universe") is very time consuming when the only thing you want is to compile-test a change that covers a small part of src/. The method offered here will save you many hours then.

This will take a lot of time, but an order less than a full buildworld. $ make _depend everything SUBDIR_OVERRIDER=<bit> TARGET_ARCH=<arch> (The underscore before "depend" is intentional.) <bit> is a part of src/ tree that you want to test (can be a list), and <arch> should be looped over with each architecture to be tested against. Example. To test if a changed bin/cat still compiles cleanly under Alpha and AMD64, e.g. due to you clamping down the WARNS level, you do this: 1. Prepare the toolchains: make toolchain TARGET_ARCH=alpha make toolchain TARGET_ARCH=amd64 2. Test changes: make _depend everything SUBDIR_OVERRIDE=bin/cat TARGET_ARCH=alpha make _depend everything SUBDIR_OVERRIDE=bin/cat TARGET_ARCH=amd64 3. You can then modify cat's sources/makefile, and repeat step #2. P.S. The syntax for PC98 would be "TARGET_ARCH=i386 TARGET=pc98".
