[Boost-users] Using boost::shared_ptr<> with G++'s -fno-rtti

Is it possible to use boost::shared_ptr<> without RTTI being enabled?  I'm
trying to port some code to the Sharp Zaurus, and its GUI libraries are all
compiled with the G++ flags -fno-exceptions -fno-rtti.  Boost seems to
support the former flag just fine, but has problems with the latter:

g++ -g -O2 -Wall -fno-rtti -fno-exceptions -o sipua/main.o -c  ../sipua/main.cpp

                 from ../sipua/radio.h:11,

                 from ../sipua/main.cpp:18:

   boost::shared_ptr<U>&)':
../libcine/boost/shared_ptr.hpp:431: error: cannot use typeid with -fno-rtti

What is the typeid call in the get_deleter functions doing?  Is there any
way to work around or disable this?

Thanks.
