把代碼從QT移植到MFC的時候，這個文件vecmat.h，出現了如下錯誤：
error C2143: syntax error : missing ',' before ')'
error C2143: syntax error : missing ';' before '}'
error C2059: syntax error : ')'
fatal error C1004: unexpected end-of-file found
等等。
vecmat.h源代碼如下:

原因是在windows的頭文件里max，min已經被定義成宏了，所以要出問題!
解決方法：
用
#ifdef max
#undef max
#endif
去掉max的定義。
min同上。
問題解決。
