[syslinux] pxelinux: 2.04 works but 2.09 doesn't

[kumon at flab.fujitsu.co.jp]

Hi,

Recently I upgraded pxelinux.0 from 2.04 to 2.09, after that the
pxelinux doesn't correctly obtain server's IP address.

The true address is 172.20.0.101, but 2.09 understand it as
172.20.0.11.  "0" is dropped.  As a result, root nfs-mount is
directed to the non existent server.

Following is the full screen dump of pxeboot by pxelinux 2.09:

When I use 172.20.0.4 as a server, it works fine with pxelinux 2.09.

Some string manipulation may have trouble.
What should I do next?
