Hi,

I guess you are using the last upload on the Vault. The last snapshot on the
sandbox includes already all these changes.

07/11/10:  11:34 Changeset [63878] by viboes 
* Take care of Boost.System break on version 1.44 * Fix "warning C4700: … 

I have made it compatible with older versions using the version to get rid
of the Boost.System interface break.

#if (BOOST_VERSION / 100 % 1000) < 44
        system::system_error( errno, system::system_category,
"chrono::system_clock" ));
#else
        system::system_error( errno, system::system_category(),
"chrono::system_clock" ));
#endif       

I will upload the last snapshot on the vault next 10th.

Hopping this helps.
Vicente
