Due to a change in Cygwin release 1.3.3 access to DOS/Win32 drives will not be supported using //x as in releases before.
Therefore I have recompiled Lyx using the newest Cygwin release and have updated all scripts and my installation instructions you can find as usual here: http://www.fh-hannover.de/mbau/tim/hentschel/lyx/index.htm If anybody using Lyx 1.1.6fix3 has upgraded to Cygwin 1.3.3 he SHOULD upgrade Lyx to release 1.1.6fix3a, too!
