Hi ! After upgrading to gcc-4.3 I got annoyed by the myriads of deprecated warnings about "hash_map" and "hash_set" especially from the BGL code. I tried to get rid of those by simply adding #define BOOST_NO_HASH to the command line and it worked. Unfortunately, it seems that trunk config does not detect hash support with msvc-8.0 and this compiler then bailed out with a macro redefinition error at config/suffix.hpp :-(( Patch to add a check for an already defined BOOST_NO_HASH (and for BOOST_NO_SLIST) attached. Comments ? Ok to commit ? Better ideas to disable hash support ? Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold ! Ingenieurgesellschaft für * voice: ++49 511 262926 57 !
