[Boost-users] [Proto] Error in FoldToList Example of Tutorial

Subject: [Boost-users] [Proto] Error in FoldToList Example of Tutorial

Dear all,
When I compile the FoldToList example defined here in Proto tutorial:
http://boost.org/doc/libs/1_45_0/doc/html/proto/users_guide.html#boost_proto.users_guide.back_end.expression_transformation.state
I get some compiler error message in GCC 4.5.1 (MinGW32, WinXP, SP3), Boost 1.42.0. For your reference, I have included the error messages in the P.S. section of this posting. Anyone here knows what's going wrong?
TIA,--Hossein
P.S.
