+
+2012-02-01 Christopher Faylor <me.cygwin2012@cgf.cx>
+
+ * fcntl.cc (fcntl64): Add introductory debug statement. Call dup3

+
+2012-02-01 Christopher Faylor <me.cygwin2012@cgf.cx>

+ write handle. Only cancel I/O when reading.
+
+2012-01-28 Corinna Vinschen <corinna@vinschen.de>

+ * cygwin.din: Fix order (DATA first).
+
+2012-01-27 Corinna Vinschen <corinna@vinschen.de>

+
+ * cygheap.h (cygheap_fdmanip::release): Simplify.
+ * dtable.cc (dtable::release): Make void again. Skip not_open check
+ since it is guaranteed to be open. Don't bother deleting here since
+ actual deletion will be handled in cygheap_fdget::~cygheap_fdget.
