2.4.26 doesn't compile? ("error: `__cmpxchg' previously defined here")

[Román Medina]

Hi,

I'm trying to compile 2.4.26 kernel but I get the following error in "make
modules" part:

I've attached the .config file which I'm using. The system is Debian
Unstable. I've compiled (older) kernels without problems.

I also tried to compile it using gcc-2.95 obtaining the same (bad) results
(I changed Makefile and replaced "gcc" by "gcc-2.95", which is the 2.95
binary in my system).

Any ideas?

Best regards,
