My understanding, which should be confirmed by someone else, such as
Bernd Schmidt:

- 2.0.x and prior kernels should only be compiled with gcc 2.7.x.
- 2.2.x is expected to work with any version of egcs.

- gcc 2.8.1 and egcs (all released versions) may silently generate bad
code for the incorrect asm constructs in old kernels 
- egcs development snapshots will error out rather than accept them.

I'm typing this on a box running 2.2.1 compiled by 1.1.1, which has
had no problems, but it doesn't have any exotic hardware or SMP or
anything.
