My first question would be "why"?

For MS thesis I'm considering Xen to port it for MIPS. as there is no PV_ops 
support available in case of MIPS so I'm forced to use old versions of Xen

Most of the time, latest upstream version, or distro-provided version
should work better instead of manually compiling an old version

It's quite common that certain software can only be compiled with
certain versions of gcc. Since you're using an old, unmaintained
version, I doubt anyone is going to fix that. I suggest you either:
- use distro-provided version (e.g. RHEL5's xen-3.1.2+), or

I 'm using RHEL5.0, and install prebuild rpm packages provided by xen.org
As directed in ReadMe after installing given RPM's, I change grub.conf as 
title My Distro with Xen (2.6.18-xen_3.1.0) root (hd0,0) kernel /xen-3.1.0.gz 
module /vmlinuz-2.6.18-xen_3.1.0 ro root=/dev/sda1 module 
where /dev/sda1 is the partition where RHEL5.0 lies.
when I rebooted and selected Xen kernel from grub menu
kernel did not booted showing following error
switchroot:mount failed no such file or directory
and it cant able to mount rootfile system  as it repoted
"could not find file system /dev/root"
would you please tell me how can I resolve this issue?- try latest stable 
version (4.1.2), or at least latest 3.x version to
see if the problem is fixed there
