Please upgrade to GCC 4.7. You may pass --disable-compiler-version-checks to configure to bypass these sanity checks. root@bulldog:~# gcc -v Using built-in specs. Target: sparc64-undermydesk-freebsd Configured with: FreeBSD/sparc64 system compiler Thread model: posix gcc version 4.2.1 20070831 patched [FreeBSD] Guess I'll have to try 10-RC5 (or wait till 10 RELEASE ??)
