Hello,

When trying to to build with a non-standard setting of HZ
(to get rid of the noise generated by my Dell Inspiron 4000):
--- linux-2.6.7/include/asm-i386/param.h.org 2004-06-01 20:19:03.000000000 +0200

I get the following error (with current Debian unstable gcc-3.3):

In file included from kernel/exit.c:18:
