Here is the info from nm:

U memset

I'm using gcc It must be a compiler bug. I compiled the file
parport_share.c with the command:

gcc -E -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -O2 \
-fomit-frame-pointer -pipe -fno-strength-reduce -m486 -malign-loops=2 \
-malign-jumps=2 -malign-functions=2 -DCPU=686 -DMODULE -DMODVERSIONS -include \
/usr/src/linux/include/linux/modversions.h -c -o parport_share.out \

That writes the output of the preprocessor the file parport_share.out. There
is just one line in the output where memset appears:

extern void * memset(void *,int,__kernel_size_t);

The line comes from the file /usr/src/linux/include/string.h.

Should I move to another compiler?
