I had the same problems, I compiled everything with gcc-2.96 on a
RedHat...

Confirmed. The problem appears with gcc-3.4.4-r1 (stable branch) and
both, vanilla-sources 2.4.30 (stable) and 2.4.32 (testing).

I compiled everything with gcc-2.96 on a

Problem:
I think the problem is the way in which gcc-3.4.4 manage recursive
inlining. sg_fill is an inline function which call itself and 3.4.4
doesn't like that.

Status:
We have our gcc ninjas working on it, hope to have it fixed soon.

Workaround:
I think is only problem of gcc-3.4.4. I can compile it with gcc-3.3.2
just fine. Since gcc is installed slotted, probably everyone who updated
the gcc compiler can change it using gcc-config and compile the kernel
with an old gcc (if needed).

Thanks guys for reporting.
