-*** Building Emacs for Cygwin can fail with GCC 3.x
-
-As of Emacs 22.1, there have been stability problems with Cygwin
-builds of Emacs using GCC 3.x.  Cygwin users are advised to use GCC 4.
+*** Building the Cygwin port for MS-Windows can fail with some GCC versions
+
+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).
