New Comment:
We are sorry, but we can not support PHP 3 related problems anymore.
Momentum is gathering for PHP 5, and we think supporting PHP 3 will
lead to a waste of resources which we want to put into getting PHP 5
ready. Of course PHP 4 will continue to be supported for the
forseeable future.

I also noticed that
PHPAPI void convert_to_long_base(pval *op, int base)
uses strtol() instead of strtoul(), which also contributes to my
difficulty.
$ip=0xffffffff doesn't equal -1, but $ip=~0 does.
Perhaps I'm just trying to do something that isn't supposed to work,
but
the results are clertainly not intuitive.

The function dechex() can be passed a negative number, which will
create a negative index into a static array. This was discoverd when
trying to manipulate IP addresses represented by integers. Any IP that
has a first octet >127 will cause this to happen. Since integers are
signed, I wonder what other areas might have a similar problem when
trying to manipulate IP addresses in this way.
Simple Example:
print(dechex(-333333));
This fix seems to correct this instance of the problem, but I fear that
there could possibly be undesirable side effect of doing this.
