  Could this be the culprit?
 
 Yes, it looks like xemacs-tags and ctags packages both install
 /usr/bin/ctags.exe:
 
 http://cygwin.com/cgi-bin2/package-grep.cgi?grep=ctags.exe

Oh boy, how long do we have this collisions?  For years, it seems.

FWIW, I'd prefer to keep Exuberant ctags since that's what is part
of most Linux installations as well.

Volker, would you mind a lot to obsolete the xemacs-tags package
in favor of the ctags package?


Thanks,

  One can see from the timestamp on the links for gcc and vim that I
  installed Cygwin on 10/18/2012.  However, it seems that both ctags
 and
  etags are old versions of the program (circa 2007) and are not the
  Exuberant Ctags version.  However, the GNU documentation here:
  http://directory.fsf.org/wiki/Exuberant_Ctags  clearly lists the
  Exuberant Ctags, although it has only been updated as of 2004.
  However, looking here:
  http://cygwin.com/packages/ctags/ctags-5.8-1-src   we see that cygwin
  has Exuberant Ctags 5.8.  Perhaps it is just a packaging issue that
  caused the old one to be present and Exuberant Ctags 5.8 to be not
  present?
  
  You can see from this thread:
  http://stackoverflow.com/questions/2634001/any-idea-why-ctags-wont-
  recurse-on-cygwin/13810472#13810472
   that I'm not the only one who stumbled onto this problem.
  Where should we go from here?  Could it just be a packaging problem?

There must be a database of package contents behind the packages search 
engine on sourceware.  If someone that has access to that DB extracts a 
raw list of file names, this command will find the other duplicates:


grep -o '/[a-z0-9]+\.exe$' filelist | sort | uniq -d

Some will be harmless, like the two ksh.exe versions.  But, maybe 
something interesting will turn up.

As long as Exuberant Ctags is a complete superset of the functionality 
in xemacs-tags, this seems like a good idea.  Anything that depends on 
xemacs-tags can depend on the ctags package instead.

I request a feature to detect package collision, and furthermore suggest 
which package to install when an user tries to run a program which is 
not installed but is available from a package.


Such feature has been implemented in Ubuntu, for example:

 This helps:
 
$ cygcheck --help
...
-f, --find-package   find the package to which FILE belongs

$ cygcheck -f /usr/bin/ls
coreutils-8.15-1

That only works on files whose package is installed, unfortunately.

http://www.cygwin.com/packages is the tool to use for this.

Cygwin supports mmap for a long time.  However,  I'm puzzled why
using POSIX message queues should be more work than implementing
the message transport from scratch.  This sounds much more error
prone than using an existing mechanism.


I have never used POSIX message queues, and that would only give me -R 
in any case, since I would still either need shared memory or a new 
positioning algorithm for -c.


Instead, I would open a lock file and use that to co-ordinate which PV 
is the first one and where the top Y co-ordinate is. I might not 
even need mmap() at all. So long as I'm using lock files for the 
terminal anyway, it seems that I might as well also use them for the 
rest of -c and -R.


So this is why I think it would be easier to use lock files and/or mmap 
than trying to use message queues.
