Standard input} 11682: Complex expression. Absolute segment

I trying to compile TGB 1.5.1 using xcode on an intel mac, version 10.4.10.
And I get the following compiler error when it reaches

../../source/console/simManager.cc
{standard input}:11682: Complex expression. Absolute segment assumed.

this spits out a bunch of these

{standard input}:27148:Complex expression. Absolute segment assumed.

then it ends with this

Command /usr/bin/gcc-4.0 failed with exit code 1

I never seen this error before any help would be appreciated
