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.
Sorry, no.
The actual type should only be returned in dirent.d_type if the info
is available at very low cost. This is not the case for Cygwin
symbolic links.
If DT_UNKNOWN is returned, lstat() must be called if type info is
required.
Quote from Linux man page readdir(3):
"All applications must properly handle a return of DT_UNKNOWN."

In this case I do not agree with this. Cygwin symbolic links are there
to emulate Linux symlinks. Therefore I expect the same behaviour.

functionality similar to a Linux distribution on Windows.''
