PLEASE TEST: Latest Cygwin snapshot == 1.5.10 alpha

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@cygwin.com, see

Thanks,
Corinna

BTW, should /dev/kmem work also?  It fails for me on Win2k '/dev/kmem:
No such device or address'.  I don't know if it's important, but here's
"ls -l /dev/kmem", just in case:
crw-rw-rw-    1 igor     Administ   1,   2 May 20 09:18 /dev/kmem

As I've reported already, this isn't entirely fixed.  Anything I can do to
help debug this?  It'd be great if this could be fixed in 1.5.10...

Other than the above, the snapshot seems to be working great so far.

No, only /dev/mem and /dev/port are working.  /dev/kmem is still looking
for a contributor.

For what it's worth, the snapshot appears to fix a problem that I've
had building CVS guile -- briefly: the built guile would (when used to
build the documentation) immediately die with an error message from
Windows.  I'd be happy to provide more details if anyone's interested.

Sigh.  My new email setup really sucks.  I found your message in the
archives but it hasn't arrived here yet.  I think that bu.edu has
various forwarding servers that just go down randomly and it takes days
for anyone to notice.  When they eventually kick the machine, I get a
bunch of old email in my inbox.

Anyway, I found your message in the archives and I think that your problem
should be fixed in the current snapshot.

And it is -- works like a charm in 20040520.  Thanks, and sorry for the
delay in testing.
