can't compile grub with network support

[Patrick HARMEL]

I'm trying to set up a boot floppy able to load a linux kernel and an 
initrd by the network (for installation purpose).
I get the sources (version 0.97), read the doc, and do.
at the top of the source tree, i first type:
./configure --enable-eepro100
then:
make
and get an error.

I check the required software but didn't noticed any problem.
I am using a Debian Sid distro

Here is information about required software
