Hi Rob,
Sorry for the last email. I clicked wrong button.
Your way to dig into the details just inspired me to find the cause of
another problem I have when compiling busybox-1.0.0.

__NR_sysfs is defined in <asm/unistd.h>, which is included in
<linux/unistd.h>. But surprisingly to find that it's NOT include in
<unistd.h> in the toolchain I use.
Adding <linux/unistd.h> to libbb/syscalls.c solved the problem.
-shawn.
