Here's another winsup snapshot.
I think we're getting ever so close now to b20 state. There are still
a few bugs that need investigating (e.g. control-C in bash in Win 98
results in a several-second hang). This snapshot fixes the skipping
every other shell script read command problem, the sed problem during
configures bug, and some other stuff. Also, mingw is now
built/installed by default and the latest patches have been applied to
the mingw headers. Finally, updated include/Windows32 headers are
included.
Most importantly though, this snapshot introduces the new Cygwin
versioning system. This will hopefully eliminate or greatly reduce
Cygwin DLL conflicts as we put out new versions of Cygwin in the
future.
Here's a brief summary of the new Cygwin versions:
* CYGWIN_VERSION_DLL_MAJOR, CYGWIN_VERSION_DLL_MINOR for the DLL
version (currently 19.6).
* CYGWIN_VERSION_MOUNT_REGISTRY: version associated with registry
mount table format. (currently 1).
* CYGWIN_VERSION_API_MAJOR, CYGWIN_VERSION_API_MINOR for tracking
non-backward-compatible interface changes. (currently 0.0).
* CYGWIN_VERSION_SHARED_DATA for tracking non-backward-compatible
changes to the shared memory areas. (currently 1).
Although the comments at the top of the file need updating, if you're
curious, take a look at include/cygwin32/version.h.
You will also note that the b20 Cygwin DLL will be named
"cygwin1.dll". This will only be incremented when incompatible
changes to the API or shared memory areas happen. Finally some
additional information such as build date will be included in the DLL
to help in debugging but which are not actively checked by anything.
Finally, note that we will probably change the way the mount table
looks in b20, removing that stupid "b15.0" version and putting the
mounts under:
Cygnus Solutions/Cygwin/mounts/<mount_registry_version>/<here>
The installer will hopefully be capable of moving entries from the old
location to the new one for people. Note that the mount change isn't
in this snapshot.
As usual, feedback on any of this is welcomed.
ChangeLog entries since the last snapshot follow.

----------------------------> snip <-------------------------------
Mon Oct 19 23:45:24 1998 Geoffrey Noer <noer AT cygnus DOT com>>
* include/windows.h: remove Objective-C BOOL ifdef, now taken
care of within the include/Windows32 header files.
* fhandler_console.cc: fix KeyEvent references in light of
changes to the KeyEvent struct in the Windows32 headers.
Update include/Windows32 header files. Changes from
Mumit Khan <khan AT xraylith DOT wisc DOT edu>, Corinna Vinschen

this with /bin/sh, bash, and ksh.
Mon Oct 19 11:19:58 1998 Christopher Faylor <cgf AT cygnus DOT com>

for writing mount information back to registry.
(mount_info::init): Remove obsolete stuff.
Mon Oct 19 10:42:17 1998 Christopher Faylor <cgf AT cygnus DOT com>

where apropriate.
* path.cc (path_conv::path_conv): Set symlink_p to a positive
value if !nofollow, negative otherwise.
(windows_device_names): Can't default to \dev\comx. \dev part
doesn't work.

the '1' when there are API/shared memory changes. Make
version.cc file every time .dll is linked. Remove datestamp
stuff.
* mkvers.sh: New file. Creates version.cc.
* cygwin.din: Export setdtablesize.
* dcrt0.cc: Remove obsolete version variables.
(build_argv): Use issep() macro rather than isspace since
isspace includes whitespace that the shell does not consider
a command separator.

structures for compatibility checking.
(dll_crt0_1): Ditto.
(__api_fatal): Renamed from api_fatal. Now always called from

fields.
* winsup.h: Regroup into sections. Add new version structure.

patch from Corinna Vinschen <corinna DOT vinschen AT cityweb DOT de>:
* fhandler_console.cc (fhandler_console::dup): reset
default_color since the console fhandler forgets its default
colorizing when it's `dup'ed.

erasing in constructor of fhandler_console.
Mon Oct 12 22:20:59 1998 Christopher Faylor <cgf AT cygnus DOT com>
