Hello everybody,

At Debian we have recently stumbled upon a "hidden"[0] clause[1] in a source 
code file included in PHP since php4. Since this clause is not free in terms 
of the Debian Free Software Guidelines (DFSG)[2] it prevents us (Debian) from 
distributing the php interpreter.

I am thereby asking for your permission to remove the clause; but I would like 
you to give permission to *anybody* and not just Debian, as otherwise it 
would be a violation of the DFSG.

Although Shawn Cokus and Richard J. Wagner stated that it would be _nice_ to 
CC them it would be nice to get an OK by them too.

When replying please send a copy of the message to, at least, the addresses in 

[0] It was not noticed until a couple of weeks ago by Jan Wagner, who reported 
the problem at http://bugs.debian.org/499471

[1]  From php's ext/standard/rand.c:
>         The original code included the following notice:
>         When you use this, send an email to: matumoto at math.keio.ac.jp
>     with an appropriate reference to your work.
>         It would be nice to CC: rjwagner at writeme.com and
> Cokus at math.washington.edu when you write.
