dt_arith would fail in Lion and Mountain Lion system when GCC version 4.2.1 is used with --enable-production. Somehow the -O optimization will fail some of the hard conversion code. Solution: This is just a temporary patch by detecting if this is a Lion or Mountain Lion system using GCC 4.2.1, then just remove the any -O option from the PROD_CFLAGS. A better fix should be deviced later. Tested: Duck(lion) and Owl (mountain lion) tested with --enable-production. Also tested in Fred and Tejeda, both Snow Leopard systems to verify there is no undesired side effect.
