That's because <direct.h> is an old, non-standard header not present on
modern POSIX-y machines.  You want <dirent.h> instead, when targetting
cygwin.  Or else your project is truly tied to Windows, and you should
be targetting mingw, in which case the question is semi-off-topic here
(other than how to properly use the mingw cross-compilers available from
a cygwin installation).

That depends on whether your code is POSIX-y and targetting cygwin, or
is tied to Windows APIs and should be targetting mingw.

A native app doesn't depend on cygwin, but that also means it can't use
the POSIX-y interface provided by cygwin.
