[Boost-users] serialization support for gcc ?

Hi, In the serialization jam file (master), I see: <toolset>gcc:<cxxflags>"-fvisibility=hidden -fvisibility-inlines-hidden" with no mention of gcc version number. gcc-3.4.4, for one, does not support that option. Does that mean that the serialization library does not support the gcc-3.x serie ? Thanks Alain
