I've tryed to remove all newly added optimize option seperately, and only remove the -mcmodel doesn't work. The resolving way is to remove all the options concerning sse3 (including -march=k8-sse3 -mtune=k8-sse3 -Wa,march=k8+sse3; use -march=k8 and -nsse3 produce the same error). I am building binutils (SVN 20100317) at that time. I have tried various way of CCFLAGS struggling to avoid this problem. In addition, file: /libcpp/files.c: Line 609-614: comparison is always false under win x64 and /gcc/emit-rtl.c: Line 361: /gcc/ggc-common.c: Line 310: /gcc/graphite-dependences.c: Line 107: /gcc/src/gcc/ira-conflicts.c: Line 125: /gcc/src/gcc/pointer-set.c: Line 67: /gcc/src/gcc/tree dump: Line 168: /gcc/src/gcc/cp/class.c: Line 6740, 6742, 6764, 6767, 6900: all have host-dependent code such as explictly cast a pointer to long (in win x64 means long long to long) and use %ld or &lx to fprintf a pointer. they cause the cc1 treat warnings as error and stop the make procedure, though they are easy to fix manually but quite annoying while making bootstrap.
