Hi all,

Here's another winsup snapshot.  This one is getting close to ready
for a 20.1 release.  Configures work on both NT and Windows 98 for me
but they're *really* slow (4 hours instead of 10-20 minutes).  But on
some machines this seems not to be a problem which is making it hard
for us to find the culprit.  Obviously this needs to be fixed before
we release the update.  ChangeLog entries since the last one follow
as usual.

        variables to remove duplication and make it possible to
        build mingw directory.

        path.h.

        patch from Corinna Vinschen <corinna DOT vinschen AT cityweb DOT de>:
        * include/sys/sysmacros.h: new file, define major, minor, makedev

Fri Nov 13 17:03:52 1998  Christopher Faylor <cgf AT cygnus DOT com>

        * dcrt0.cc: Reflect a variable name change.
        * fhandler.h: *::ready_for read takes an additional argument.
        * fhandler_console.cc (get_non_ascii_key): New function derived
        from fhandler_console::read1.
        (fhandler_console::read1): Use new function.
        * select.cc (*::ready_for_read): Add new "nonblocking" argument.
        (peek_console): Be more diligent in detecting when a usable
        character has been entered or false positives will be returned.
        (fhandler_tty_common::ready_for_read): Detect attempt to perform
        a "background" read.

        when an fd has data ready to be read.  Actual reads happen in
        the main thread.

        the read_ready_thread to indicate when data is ready to be read.
        Gut the read_thread_info class since it no longer needs to return
        much information.
        * winsup.h: Reflect above changes to read_thread_info.  Rename
        to read_ready_thread_info.

Fri Nov 13 10:59:43 1998  DJ Delorie  <dj AT cygnus DOT com>

        * Makefile.in: "make" uses new "ld -shared" by default internally.

Fri Nov 13 00:58:38 1998  Christopher Faylor <cgf AT cygnus DOT com>

        * spawn.cc (find_exec): Make sure that return value is correct
        in all cases.  Document.
        * fhandler.h (fhandler_tty_common): Give unit number to constructor.
        * fhandler_tty.cc (fhandler_tty_slave::fhandler_tty_slave): Give
        unit number to descriptor.  Create correct UNIX path name for
        tty so that ttyname() will work correctly.
        * select.cc (fhandler_tty_common::ready_for_read): Don't worry
        about read_for_read since the tty read routines are already
        interruptible.
        * syscalls.cc (_read): Reset read thread events on signal.

        patch from Mumit Khan <khan AT xraylith DOT wisc DOT edu>:

        * configure.in: Add --enable options for various cygwin defines
        including preliminary thread-safe defines.
