As requested by J Greene, a report for the fix of pcntl_signal on Linux. Also the pcntl_signal() function
fails when giving a function with this error msg:

Warning:  Cannot convert to ordinal value in /raid/Files/Heyes-Computing/development/fork.test.php on line 25
/raid/Files/Heyes-Computing/development/fork.test.php(25) : Warning - Cannot convert to ordinal value

This has to do with the fact that SIGCHLD+SIG_IGN was never in the posix standard. I will need to write a workaround for this under linux. Until that point, linux users must catch the handle and wait on the child.

Have not reproduced the ordinal warning message yet, will investigate ...

Just wamted to give you an update that I have not had much time to work on this lately, but I am planning on getting to it as soon as I can.

Thanks,

Unfortunately it appears that linux does not support SA_NOCLDWAIT, which is the work around I was planning on implementing. If and when they do add support for it, I will add support for it into pcntl.
