You can ignore this the stuff you want will build. I've submitted diffs for both libffi/boehm-gc that will allow the java stuff to be built.
-----Original Message----- I'm trying to build gcc 3.2. The very first thing that comes out is the following message: *** This configuration is not supported in the following subdirectories: target-libffi target-boehm-gc target-zlib target-libjava (Any other directories should still work fine.)
