I really don't think that that is a good idea at all, especially when
the newest binutils takes care of that. If he's going to be upgrading to use
the newer kernels, he will be needing to upgrade a lot of things (modutils,
gcc, libc, sysklogd, gpm, what have you). taking out the -k in rules.make to
try to get backwards compatibility, IMHO may be a big hazard, and may cause
other things to break. I remember there being an HTML-ised shopping cart of
things to get to migrate from 1.2.13 to 2.x, but the URL escapes me. Also,
reading linux/Documentation/Changes would help on this as well.

Just my thoughts.
