Dear Igor, Nice to hear from you, and thanks for the clarification!
I understand your explanation of the difference between gvim and vim. But there is still a mystery.
In my previous installation of cygwin, no such problems arise. The difference is that my previous system was Windows 2000 and my current one is Windows XP. Can you explain this?
Thanks, --Chee

Dear Igor,
How are you? I noticed that you are an active developer of cygwin. I really liked this platform and our Core Library is developed on this mainly. I have a question:
In my recent (June) installation of cygwin, there was an annoying bug -- many of the files that I create are automatically given the execute permission. [Since my "ls" will automatically show me which files are executable, this is VERY annoying.] But this behavior is not universal. If I have a non-executable file, and I exit it using gvim, the file will become executable. But using vim, it remains non-executable. But I don't think the program is with a bad installation of gvim, because this phenomenon shows up in other places.
Heard of this bug before?
Thanks, Chee
Hi, Chee,
Great to hear from you.
I'm redirecting this reply to the general Cygwin list, mostly to get this into the archives (because I know others are having this same problem). Also, this brings your question up before a large body of expertise -- perhaps someone else will find something I've missed.
This is not a bug, but rather an artifact of the default permissions files
get when written by Windows programs. Gvim is a pure Windows program, in
contrast with vim, which is a Cygwin one. Also, vim writes files
in-place, whereas gvim creates a new copy -- hence the change in
permissions. Unfortunately, there isn't anything you can easily do to fix
this. I have a script (attached) that I run periodically on my system to
fix the executable permissions. It's not foolproof, but it's better than
nothing (and it should err on the conservative side).
Igor
