C++：錯誤“error: off64_t does not name a type”

MinGW的bug,使用-std=c++11, 有可能出現, 修改{MinGW dir}/include/io.h文件,

使用:

__CRT_INLINE _off64_t lseek64 (int, _off64_t, int);  
__CRT_INLINE _off64_t lseek64 (int fd, _off64_t offset, int whence) {

代替:

__CRT_INLINE off64_t lseek64 (int, off64_t, int);  
__CRT_INLINE off64_t lseek64 (int fd, off64_t offset, int whence) {

即可.
