Hi,

The dirent.d_type value for Cygwin symbolic links is 0 (DT_UNKNOWN). The 
value is 10 (DT_LNK) for Windows native symbolic links. I think d_type 
should be 10 for Cygwin symbolic links too.


Example program. Run it in a folder with a Cygwin symbolic link and a 
Windows symbolic link (create with mklink command in an administrator 
command prompt).


#include <dirent.h>
#include <sys/types.h>
#include <unistd.h>
#include <stdio.h>

int main() {
    DIR *dirp;
    struct dirent *dp;

   dirp = opendir(".");
   dp = readdir(dirp);
   while (dp) {
     printf("%s %d\n", dp->d_name, dp->d_type);

     if (dp->d_type == DT_LNK)
        printf("SYMLINK");

     dp = readdir(dirp);
   }
   closedir(dirp);

   return 0;
}
