I have recently tried to re-install linux on my laptop (arch linux this time) and had problems when it came to recompiling the kernel.

I copied the .config from my previous install and tried to use that, but I get the following errors during the make bzImage stage:

What could be causing these errors?

Was the .config from a different version of the kernel?

Did you still run make menuconfig? You should always run it if you copied the .config from another version. Newer or older.

I think it may have been from an earlier version of the kernel - I might try and run make oldconfig and see if I can get it working that way

GCC before 3.3.3 had "something" missing so that prototypes' attributes could be different from attributes declared at the function body.
Since now GCC 3.3.3 correctly emits a warning whenever the prototype doesnot match the function UP TO THE CHAR, it barks out.
And Linux 2.4.x is affected by this now.
I have put up a fix that solves this.
fastcall.diff
Even though it's diffed against 2.4.21-SuSE202, it should work against most other 2.4s. If not, well, you can only correct offending hunks by hand :-)

Would be nice to hear if it helped anyone... because it gets downloaded often.

I've been using the stock arch kernel now - so I haven't downlaoded your fix because, as yet, i haven't needed a fix for the laptop...

But thanks for doing it - I'm sure it'll be a help to others!

There are no further compiling problems for Linux 2.4.28 (the vanilla one from kernel.org) using GCC 3.3.4. I therefore stopped supplying a patch. If anyone is using GCC 3.3.3, I would like to hear back if it is still broken there.
