With this exception, the other changes I made were fixing existing problems
that gcc-2.95.3 neglected to comment on. There are still macros with
token concatenation bugs, and they are even bugs under 2.95.3. Are we not
allowed to fix those just because gcc3 highlights them?
And with all due respect to your testing procedures, it isn't exclusively
your job to get the kernel to work with gcc-3. If you can land a valid
compiler in the tree then you have succeeded. The rest of the tree can
attend to itself - that is why our project is distributed.
For what its worth, a kernel built with an unpatched gcc-3.0.1 release
boots and runs fine on my laptop. I'm not expecting miracles, but the
basic functionality seems to be there. Our usual problem area - the inline
stuff that the mutexes use - doesn't seem to be broken either.
Heck, when you get the damn thing imported, I'll buy you a round (or six)
at a decent pub.
Cheers,
