Re: mc-4.5.55 is now part of the Cygwin net distribution

Hi Pavels,

I think it will be a very good idea to port the latest snapshot.

I built MC from snapshot about 3 months ago and I was having the following
0. regex.c - fixed by me
1. subshell dies after few Ctrl-O, then mc dies. It happens very quickly
under rxvt or xterm, but if started from DOS box, it works for quite a
while, but then it still eventually dies.
I doubt this is a cygwin problem, because the well known unix  "screen"
works under cygwin without any problems, although it also uses pty's. Maybe
it is a good idea to see the sources of screen and find out how the subshell
must be done.

2. MC barks on  'pagefile.sys' :
File 'pagefile.sys' exists but can not be stat-ed: Permission denied
This is actually a general problem, I saw it on unixes as well, but it is
very annoying under cygwin.

3. editor and viewer don't work properly on filesystem, mounted in text
mode, editor even corrupts files in DOS encoding.
The solution is to change mc editor to open all files in binary mode using
"w+b" method.
Even if to do so, there is a problem with ^M's at the ends of lines, which
are invisible and can be easily mixed up with text and screw up the file.
This is also common problem with unix if one has to edit files in dos
I was having a lot of trouble because of this since all C++ files in our
clearcase are in DOS encoding.
I saw some remains of code in MC which are supposed to do some CR-LF
translation, I tried to enable it, but mc just crashed.
Pavel, any suggestions how this can be fixed properly?

4. The border lines are screwed up while running inside DOS box or rxvt. Not
a big deal, but not aesthetic.

I would be very happy to take part in cygwin port, I will try to fix the
