Hi,

since we're heading with big steps towards Cygwin version 1.5.10, I'd
like to encourage as many of you as possible to give the latest developer
snapshot a test.

Many bugfixes and some interesting changes have been made and some new
functionality have been added.  The most important patches are listed below.

As usual, send bug reports to cygwin AT cygwin DOT com, see
