Advantage is in full integration of Emacs and Cygwin tools.
Watching this list I found that many people use Cygwin Emacs package.
Or is there not much upside to a user using the default 23.2 zip package?
I use native GNU Emacs. It's GIU look more pretty and Emacs understand
Windows-style path is good thing when you need "goto-error" feature
for MSVC compiler, etc...
With "cygwin-mount.el" native Emacs understand Cygwin-style path.
Also I use:
(when (eq system-type 'windows-nt)
;; Workaround for Cygwin shell, when set 'CYGWIN=noglob'. By default
'shell-quote-argument'
;; quoted by double '\' chars, this cause failure.
(defun shell-quote-argument (argument)
(concat "'" argument "'")
)
;; Workaround for Cygwin when 'shell-file-name' is 'bash'.
(setq null-device "/dev/null")
)
;; Use shell from Cygwin/MinGW.
(setq shell-file-name "bash")
(setenv "SHELL" "/bin/bash")
(setq explicit-bash-args '("-i"))
(setq explicit-sh-args '("-i"))
and some utils like "hg" require wrapper to make it .exe. Just compile:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#define MAX_STR_LEN 500
int main(int argc, char **argv)
{
char cmd[MAX_STR_LEN] = "";
char **cmdarg = malloc((argc+1) * sizeof(char *));
char *start, *end;
start = strrchr(*argv, '/');
if (start)
start++;
else
start = *argv;
end = strrchr(start, '.');
if (end) {
memcpy(cmd, start, end - start);
cmd[end - start] = '\0';
} else
strcpy(cmd, start);
for (int i = 0; i < argc; i++)
cmdarg[i] = argv[i];
cmdarg[argc] = NULL;
return execvp(cmd, cmdarg);
}
and take name to executable as shell/perl/python/... script
with ".exe" suffix.
Also I have troubles with quoting of " and {. For example
to make vc-hg.el work properly I patch it:
--- vc-hg.el 2011-01-08 19:45:14.000000000 +0200

That's all you need to friend native Emacs with Cygwin.
I am happy with this setup for 3 year with native Emacs from 22.1 to 23.3.
