This bug is already fixed:

krivenok_at_develop2 10:36:35 ~/dev_builds/boost-trunk/boost/date_time $ 
svn -r 49505 log
------------------------------------------------------------------------
r49505 | andysem | 2008-11-01 13:34:04 +0300 (Sat, 01 Nov 2008) | 7 lines

Fixed various issues, including missing includes, missing IO operators
for local time, windows.h inclusion on Windows, compilation failure on
GCC 4.3, a number of warnings on GCC and MSVC. Added a new format
specifier %O to format and read more than 99 hours in time durations.
All exception throwing moved to boost::throw_exception in order to
support builds with exceptions disabled.

To fix it with boost-1.37 edit the file boost/date_time/tz_db_base.hpp 
as follows:

-      typedef dst_adjustment_offsets<time_duration_type> 
dst_adjustment_offsets;
+      typedef 
boost::date_time::dst_adjustment_offsets<time_duration_type> 
dst_adjustment_offsets;
