I have Sun E280 with Solaris9, single CPU, Is it advisable to compile bind 9.2.3 not with defaults but with -m64 CFLAGS and --enable-threads. Doesn't bind 9.2.3 support threads by default? Is the 64-bit code safe to run or shall I stick to default 32-bit binaries. I have gcc 3.3.2 with 64bit support. Ladislav
