I gave a pointer how to unify the two functions (although I missed the > fact that the member variables are named differently). I'd appreciate if you > did not make it more difficult than necessary to factor out common code. Because the stat structure is different and handling exceptional situation is different, I don't think we can have a single do_stat function for Cygwin and MinGW. Yet, perhaps, it is possible to move some code in common functions even if it is just a few lines. The first candidate is win_attr_to_st_mode(), which converts dwFileAttributes returned by GetFileAttributesExA to st_mode. Another possible function is that obtains and converts Win32 error code to errno value. These function can be placed into some common header (for example, win32.h), which will included by both implementations. Does it make sense?
