Due to insufficient usage of "volatile", memory barriers, et al.,
Linux 2.0.xx may appear to work correctly with 2.0.xx kernels, but it WILL
fail sooner or later, depending on what you do with it (networking / device
drivers seem to be particularly vulnerable).
There are patches around, but it's unknown (to me, at least) whether they
fix all of the problem, and they'll not get integrated into 2.0.xx anyway
(according to Alan Cox).
Therefore, 2.0.xx should NOT be compiled with egcs-1.1. Any regression
testing with 2.0 is, IMHO, essentially wasted effort.
