add fdisk --> compilation error!

Hi all,

Here are some details about my problem (selection of "fdisk" in menuconfig)

In compiling uClinux by running Cmd: make NON_SMP_BUILD=1

Here is the error obtained:

fdisk.elf2flt(.text+0x4f64): In function `xbsd_readlabel':/uClinux-dist/user/fdisk/fdiskbsdlabel.c:732: undefined reference to `bcopy'

make[1]: *** [all] Erreur 2

Are there other features to enable (or not) when using fdisk?

Someone he knows why I have this error?

thanks!
