RE: Problem installing CPAN module

Thanks a lot Lasse - your PID_ZOMBIE -> PID_UNUSED rename trick worked a
treat.

Actually I put down those versions numbers attempting to narrow down the
cause of PID_ZOMBIE problem. Chris suggested a workaround to the Win
PID/Cygwin PID problem - I recorded this in the bugs I logged in both the
CPAN and SourceForge bug lists (not sure where the maintenance for this
module is taking place): 
http://rt.cpan.org/NoAuth/Bug.html?id=12840
http://sourceforge.net/tracker/index.php?func=detail&aid=1222359&group_id=81
217&atid=562305

In case someone else finds it useful, I had hit a problem with calling
Proc::Killfam in Perl - it died with a "can't stat /dev" error on Cygwin. 

The following script by Igor Pechtchanski fixed the problem.

Thanks Igor! 

Cheers,

Hmm... This rings a bell... *digging through old CPAN build cache*

Yup, here it is... Appearantly the cygwin.h include file changed at some 
point and the PID_ZOMBIE definition disappeared. Seems like the 
PID_UNUSED definition replaced it though. At least it has the same value.

So, I just replaced PID_ZOMBIE with PID_UNUSED in Proc::ProcessTable's 
os/cygwin.c and voila! It builds...

Whether that's the correct definition to be used there, I have no idea 
but it seems to work fine...

I actually thought I had submitted a patch for this but I must have 
forgotten...

It seems the problem with Proc::ProcessTable picking up the wrong PID 
(i.e. Win PID instead of Cygwin PID) is still around... I'm not really 
familiar with cygwin's internals so I'm not sure what to do about that...

But at least it builds now.. ;-)
