Hi
I'm back in business :)
I switched from native Win32 to cygwin because of the non-matching
Win32 permissions.
Cygwin ACL's are sometimes fucked up by inheritance.
So I have several improvements.

From: Reini Urban <rurban(a)x-ray.at>
Date: 2009/6/24
Subject: xemacs winclient improvements
To: The Cygwin Mailing List <cygwin(a)cygwin.com>
Several xemacs ideas:
* I added -mwindows to the winclient linker step which results in a
much improved winclient.
I'll take this patch to xemacs-patches by myself.
* parseCommandLine() does not work on cygwin this way.
It uses the Win32 API to find files, and should be special cased to
use the POSIX API.
I'll discuss this at xemacs-beta
* xemacs-21.5.28-3 uses slow defaults:
Compiling in support for extra debugging code.
Compiling in support for runtime error checking.
WARNING: ---------------------------------------------------------
WARNING: XEmacs will run noticeably more slowly as a result.
WARNING: Error checking is on by default for XEmacs beta releases.
WARNING: ---------------------------------------------------------
hmm. 21.5.28 is stable for me and upstream. maybe remove this.
* build failure on 1.7:
In file included from
/usr/src/xemacs-21.5.28-3/src/xemacs-21.5.28/src/console-msw.h:41,
from
/usr/src/xemacs-21.5.28-3/src/xemacs-21.5.28/src/cmdloop.c:43:
/usr/src/xemacs-21.5.28-3/src/xemacs-21.5.28/src/syswindows.h:500:
error: conflicting types for 'wcstok'
/usr/include/wchar.h:92: error: previous declaration of 'wcstok' was here
make[1]: *** [cmdloop.o] Error 1
This needs a patch upstream. Maybe I'll take it upstream.

Forget the previous attempt. It double-freed an arg.
This patch works now fine.

Hi, Reini -
Thanks for sending this along. I had the start of a similar patch in
my workspace, but yours goes further.
Sorry this has taken awhile for my feedback. I have a couple of comments:
1. Please explain the '260 + 1001' values in your patch. In cygwin
1.7, PATH_MAX is 4096, shouldn't you use that?

+ if (err)
+ free (arg);
+#endif
if (ret)
break;
2. There was an unconditional
free (arg);
there. Did you mean to remove it?
- Vin

4096 can also be used.
I just took this arbitrarily looking logic 260 + 1001 from the cygwin
sources itself
to precalculate the expanded length.

This last
- free (arg);
+#ifdef __CYGWIN__
+ if (err)
+ free (arg);
+#endif
was causing me headaches and crashes. arg is already freed, because
arg = fullpath; for cygwin only.
Just in the err case arg is a single unfreed pointer.
Maybe it should be documented in the source also.

Attached is the 3rd version of my winclient patch.
This version correctly resolves a xemacs symlink and properly converts
the dde path to windows.
I just used /usr/bin/which and /usr/bin/cygpath which is in the cygwin
base install.
