I went with the GCC 4.7 option you gave me. Worked instantly. Thanks.
Though one problem, i signed the tx on the offline machine (0.96.4) but for some reason i am not allowed to broadcast it on my online machine (0.96.2)
I'd update the online machine to 0.96.5 and see if you still have the same problem. Note that there are signing fixes in 0.96.5 that aren't in 0.96.4 and you might need those on the offline machine.
