Is there an alternative download site for IPC package?

Is there an alternative download site for IPC package?

[Brian K. Smith]

I was wanting to down load the IPC source package from 
http://www.multione.capgemini.fr/tools/pack_ipc/

but the server is not responding. Is there an alternative? or could
somebody email it to me?

I appreciate any help.

Eric -
  No problem. I'll update the cygipc package later today, which both
patches. Thanks for the feedback.

  Sure, I'll apply this and update the packages on the website. Thanks for the
feedback

Also, please apply my included patch.  It moves a private structure
definition from
the public include/sys/sem.h (where g++ doesn't like it) into a private
header.

Thanks.

Can you apply also the included patch? It was developed by some PostgreSQL
hackers (details can be found in pgsql-hackers mailing list) and corrects
the behaviour of the original version (which used some variables
uninitialized, etc). And I think the version number could be taken to 1.04.

Re: Is there an alternative download site for IPC package?

[Charles S. Wilson]

I've also mirrored it at http://cygutils.netpedia.net/ . My
version has a few extra patches added -- for instance, the
missing  ftok() was shamelessly copied from glibc-2.1.2 --
but has had very little testing.
