Problems:
========
I get runtime errors simply from linking against 
libboost_filesystem.so.1.44.0. Here is a stacktrace:

export LANG=C removes the exception, but that's not a very good 
solution, of course...

I also encountered some new (compared to 1.41) warnings when I built 
some of my own code:

Algorithm:
------------------
Calls like
boost::local_time::local_date_time localTime(date, timeOfDay, timeZone_, 
boost::local_time::local_date_time::NOT_DATE_TIME_ON_ERROR)
lead to
boost/algorithm/string/detail/find_format_store.hpp:74:18: warning: 
unused parameter ‘Input’

Since that should be trivial to be fixed, I'd be grateful, if the 
warning could be removed in the release version :-)

Archive/Serialization:
----------------------------
boost/archive/basic_archive.hpp:57:33: warning: type qualifiers ignored 
on function return type
boost/archive/basic_archive.hpp:93:33: warning: type qualifiers ignored 
on function return type
boost/archive/basic_archive.hpp:130:27: warning: type qualifiers ignored 
on function return type
boost/archive/basic_archive.hpp:164:38: warning: type qualifiers ignored 
on function return type
boost/serialization/collection_size_type.hpp:40:33: warning: type 
qualifiers ignored on function return type

Again, these are trivial to be fixed by removing the obsolete const 
qualifier. Please, with sugar on top :-)
