Re: [Mingw-users] slow msys startup (was emacs with windows)

I normally use msys.bat to start the shell. But I experienced the delay when I started a windows CMD window and just stared bash.exe. Or when in emacs and did the compile command (in that case, I started emacs from an msys shell that was started using msys.bat). Also, I recently installed mingw, using the app get program as instructed on the site. But I did have cygwin installed at the time. It is certainly possible that something funny happened in the install. But I think it would have to be some conflict with an existing software package of some form since I really think that the mingw install was by the book. In all, getting very cool, but it has taken quite a bit of time. And kind of a litany of "little thing". Like emacs' next-error function not getting the file name correct...

This is odd, because when I start MSYS, Wireshark shows no packets of any kind. I'm running MSYS using the msys.bat file, which brings up a cmd.exe (i.e. I'm not using any kind of console application) with bash running in it. What are you doing?
