Hi Andrew,

The problem is reproducible with all compilers that I have access to:
gcc-4.1.2 and gcc-3.4.6-5 (Debian, boost 1.39.0)
The error message:
"/usr/usuaris/doctorat/dmitry/include/boost_1_39_0/boost/property_map.hpp:161: 
error: assignment of read-only data-member 
`boost::ReadablePropertyMapConcept<main()::cWeightMap, main()::Edge>::val'"

MSVS 2005, Windows XP, boost 1.37.0:
d:\boost\boost_1_37_0\boost\property_map.hpp(162) : error C2166: l-value 
specifies const object
         d:\boost\boost_1_37_0\boost\property_map.hpp(159) : while 
compiling class template member function 'void 
boost::ReadablePropertyMapConcept<PMap,Key>::constraints(void)'
         with
         [
             PMap=cWeightMap,
             Key=Edge
         ]
