[boost] question regarding g++ 4.3.2 and maybe others

On my local system I'm trying to build/test with gcc 4.3.2. The library builds with nocomplaint, but when I build/run the tests I get:Info: resolving typeinfo for boost::serialization::detail::extended_type_info_typeid_0 by linking to __imp___ZTIN5boost13serialization6detail27extended_type_info_typeid_0E (auto-import/usr/lib/gcc/i686-pc-cygwin/4.3.2/../../../../i686-pc-cygwin/bin/ld: warning: auto-importing has been activated without --enable-auto-import specified on the command line. This should work unless it involves constant data structures referencing symbols from auto-imported DLLs.) My site-config.shows gcc : 4.3.2 : g++-4 ;should it show some compile time switch besides this? Or ?Robert Ramey
