Are you sure disabling wide character support is really the solution, or 
that it is really fully disabled?

For the 2.95.x test at 
http://boost.sourceforge.net/regression-logs/cs-linux-RC_1_30_0-links.html#config_info%20gcc2953, 
BOOST_NO_STD_WSTRING is already defined, so presumably wide character 
support is already disabled.

Look at the error messages from date_time testperiod below, and the source 
code lines they refer to. At least directly, they don't seem releated to 
wide character support.
