@Christian: Can you please review this commit?

By the way, mode_t is also defined in import.c:

#ifdef MS_WINDOWS
/* for stat.st_mode */
typedef unsigned short mode_t;
/* for _mkdir */
#include <direct.h>
#endif

And stat_filemode() should detect integer overflow. mode_t is a 32-bit unsigned integer on Linux, and now a 16-bit integer on Windows, whereas stat_filemode() uses an unsigned long (which 32 bit on Windows, and 32 or 64 bits on Linux).
