5774,Boost Signals 1.48 gcc 4.6.1 error,ramon.casellas@…,Douglas Gregor,"Dear Boost Signals mantainer

The component no longer compiles (See error below)
Ubuntu oneiric
Boost trunk
gcc 4.6.1 - ./b2 address-model=64 cxxflags=-std=gnu++0x

Apparently std::map expects either a map::const_iterator or a const ref to map::key, 

Thank you,

R.
