vc6编译，debug模式，缺省无优化，可以正常生成exe；
但是选择按速度优化，就报错：
--------------------
Configuration: rsatest - Win32 Debug--------------------
Compiling...
Command line error D2016 : '/ZI' and '/O2' command-line options are incompatible
Error executing cl.exe.

rsatest.exe - 1 error(s), 0 warning(s)

直接选择release模式，则出现
--------------------Configuration: rsatest - Win32 Release--------------------
