I applied the patch which adds the CW_SYNC_WINCWD code and I updated
the documentation accordingly.

I uploaded the rewritten chapter about using the Win32 file API here:

  http://cygwin.de/cygwin-ug-177/using.html#pathnames-win32-api

Please have a look.

As for the documentation about CW_SYNC_WINENV, it's already in the
"official" docs at

  http://cygwin.com/cygwin-ug-net/setup-env.html#setup-env-win32


HTH,
Corinna
