Compile problems with 2.4.20pre kernels

Hello all,

I'm not sure, but I think that there are compile problems since the 2.4.20pre-kernels with pcmcia-cs package 3.2.1. I get the following warnings:

../include/linux/kernel.h:10: warning: `EXPORT_SYMTAB' redefined

Is this a problem of the kernel haeders or should the pcmcia-package be fixed?
