-Building Emacs 22 with Cygwin builds of GCC 3.4.4-1 and 3.4.4-2 is
-reported to either fail or cause Emacs to segfault at run time. In
-addition, the Cygwin GCC 3.4.4-2 has problems with generating debug
-info. Cygwin users are advised not to use these versions of GCC for
-compiling Emacs. GCC versions 4.0.3, 4.0.4, 4.1.1, and 4.1.2
-reportedly build a working Cygwin binary of Emacs, so we recommend
-these GCC versions. Note that these versions of GCC, 4.0.3, 4.0.4,
-4.1.1, and 4.1.2, are currently the _only_ versions known to succeed
-in building Emacs (as of v22.1).
+As of Emacs 22.1, there have been stability problems with Cygwin
+builds of Emacs using GCC 3. Cygwin users are advised to use GCC 4.
+
+*** Building Emacs 23.3 and later will fail under Cygwin 1.5.19
+
+This is a consequence of a change to src/dired.c on 2010-07-27. The
+issue is that Cygwin 1.5.19 did not have d_ino in 'struct dirent'.
