+LyX should be easy to compile, but you must use the most recent cygwin
+dll (version 1.5.20-1 as of July 2006) because the qt3 library in the

 To build lyx for cygwin, you should
 
   * install (using the cygwin setup program) at least the following
     packages and all other packages pulled in by dependencies:
 
-    aspell        grep       libintl1       qt3-bin      tar
-    coreutils     jbigkit    libintl2       qt3-devel    libiconv
-    diffutils     jpeg       libpng         python
-    gettext       libintl    libpng2        sed
+    aspell        gzip       libiconv     qt3-bin
+    aspell-dev    jpeg       libpng       qt3-devel
+    gcc           libintl    libpng2
+    gettext       libintl1   jpeg
+    gettext-devel libintl2   python
+
+  * install aiksaurus (http://aiksaurus.sourceforge.net/, optional):
+    There is no cygwin package for aiksaurus, so you should build it from
+    source. However, aiksaurus builds smoothly on cygwin.
 
   * run scons as you would do under linux.
