Re: [Boost-users] Serialization - compile warnings with with text_iarchive.hpp and demo.cpp

This compiler version is the only one that gives this warning.  I've tried
to address it.  I don't know if its a real problem or what.  Anyone who can
figure this out can let me know what to do about it.  I am sure its
harmless.  In the meantime you could disable the warning with a command line
switch.
