I've booted linux-2.1.117 on i586 UP, compiled with egcs-19980816 +
binutils-2.9.1.0.10, and so far it looks like it works fine (just lilo gets
screwed up because since 2.1.116pre2 something changed the geometry
reporting of disks or something such, just getting "LI" on boot).
At least with the latest egcs snapshots, I've rarely had problems with
compiling 2.1.xx kernels.
