thanks for your advice martin, but my intent is to compile the netbsd kernel using some kind of toolchain under gnu/linux.

i wish to help the netbsd project by contributing efforts toward migrating existing older code to c99.

the problem at my end is that i have a low-end laptop so i can't run virtualisation software to work with netbsd atop my ubuntu install (which is the only native unix-like system supporting all of my hardware).
