This issue relates to the MMU version of the mb-linux-gcc tools.  I'm
guessing you are using RedHat (or CentOS) v 4.00?

The MMU tools were built on a CentOS 5 workstation, and are thererfore
linked against newer versions of the standard C libraries.

RH/CentOS 4 are really very old now, possibly even out of support life
from both vendors, so there are plenty of good reasons to upgrade.

Regards,

John
