[ltt-dev] UST 0.3 released

[Thirumalai]

Hi,
    Yea. can you just tell me when this error will occur. when i searched 
for this error on net i.e ": undefined reference to 
`__sync_sub_and_fetch_4'" it is giving me some compiler options need to be 
mentioned. But even we mentioned that option, the problem persists.

Regards,
T.
